Multiple encryption news shown in messages - whatsapp

I recently upgraded to the last version of Whatsapp.
In some chat It shows encryption news several time (3-4 time on the same chat).

If it's a group it will show once per member of the group. If it's a regular conversation I have no clue

How can I send scheduled messages to multiple Telegram groups?

I've added the Telegram Bot to multiple groups as an admin, I registered the Bot in IntelliJ using Java like it is described here, so I can receive and send messages. What I need to do now is send a message like:
"TODAY IS <DAY_OF_THE_WEEK>, THE BEST DAY OF THE WEEK!"
plus some animation (a different one for each day of the week) to all of the groups every day at a certain time. I am new to all this and would really appreciate the help. I'm not even sure whether I should use Java or another language to do that. I picked Java only because it was used in the tutorial and I wanted to follow the instruction directly without having to change anything in the process.

How to track whatsapp online status of unsaved contacts programatically

Over searching, I found various solutions such as -
1 - Web Scraping using selenium but that is a very inefficient way to track multiple contacts
2 - Using store object. That was one of the best ways to track WhatsApp online status for multiple numbers but after the recent update, WhatsApp has stopped showing the online status of unsaved, unchatted contacts due to which all these methods have failed.
but I wonder how various applications like -
. https://chatwatch.net/
. https://play.google.com/store/apps/details?id=com.familog&hl=en_IN&gl=US
are still able to track the online status ?
After 6-7 December update, you can't.
Your ways:
Mock the XMPP Protocol
Create a real device (like emulator or android phone) and get the data on client.
Create a real device (like emulator or android phone) and get the data from Whatsapp Web.
Mock the Whatsapp Application.
Man in the middle attack to whatsapp application.
These ways deprecated because after 6/7 December Security Update if you don't have whatsapp chat history with this number, you can not subscribe his presence.
After today, if you want to track someone you have to chat with him. If you message the person you will follow before following, this will be detected by whatsapp and you will get banned.

Telegram CLI/BOT all implicit limits

I want to send OTP , first to Telegram with usual SMS fallback.
Therefore i have to detect read callback of OTP message from user only with telegram cli API, unfortunately(Telegram bots doesn't provide read ack. feature).
There is no any concrete info in Telegram.
Is there any limit related to telegram bot (and telegram cli) subscribers(contacts) count? Except report spam.
Also what is the limit with native telegram api sendMessage? Which density i have to keep to not banned? Also do i need more numbers or accounts for this?
I searched everywhere and can't find relevant numbers although there are some users with plenty number of accounts.
Thanks for help!
UPDATE
Limitations on bot like 30q/sec and etc. is explicit in FAQ. i have to know all other limitations, especially on CLI(max contacts, requests frequency limit). For example, i have to know is this number registered in telegram - This is possible only with cli.Therefore i don't want to abuse platform restrictions, cause of commercial cause. Glad to hear more official ways.
You can check out Bot FAQ:
If you're sending bulk notifications to multiple users, the API will
not allow more than 30 messages per second or so. Consider spreading
out notifications over large intervals of 8—12 hours for best results.
Also note that your bot will not be able to send more than 20 messages
per minute to the same group.

Windows Phone Dashboard Showing No Downloads

I have recently (only two days ago) published an app in Windows Phone Store and want to track the download counts. When I enter Windows Phone Dashboard I can see reviews, but in the quick stats it says that "There haven't been any app downloads in the last 30 days.". I can also see logins in the dashboard of the API that I am using so there must be some downloads. Does it take some time (if so how long) for downloads to be seen in the reports or is there some kind of a glinch (which I doubt) in the dashboard?
Thanks for your responses.

Auto-Renewable Subscriptions: Detecting Gaps

I'm developing an app for providing digital magazines and other periodicals. for integrating auto-renewable subscriptions and a lot of research, I came across the problem of detecting gaps in a subscription.
let's say a user subscribes for a month, opts out for half a year and subscribes again afterwards. using the apple-recommended server-based architecture for building audit trails and the whole receipt stuff, it would be pretty straightforward to track a user's subscription history. however, if there's no user-triggered transactional activity during the unsubscribed period, we will never receive an expired return value. as a consequence, the app will identify a valid subscription and unlock any content which was released when there was no actual subscription.
I'm not sure if I'm missing an important point, since I haven't found any helpful information on the web so far.
thanks in advance!
What about scheduling a cron job on a server, that will verify all current receipts once per day? Or maybe you found another working solution for that?
