Answer 1

Go to Firebase console > click your project > cloud firestore > rules.....Edit the timestamp date to a date that you want, probably a future date. Because for me the timestamp date had already passed so I had to adjust to a more future date. Dont forget to change the version of your rules too.
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
// This rule allows anyone with your database reference to view, edit,
// and delete all data in your Firestore database. It is useful for getting
// started, but it is configured to expire after 30 days because it
// leaves your app open to attackers. At that time, all client
// requests to your Firestore database will be denied.
//
// Make sure to write security rules for your app before that time, or else
// all client requests to your Firestore database will be denied until you Update
// your rules
match /{document=**} {
allow read, write: if true;
allow read, write: if request.time < timestamp.date(2022, 12, 30);
}
}
}
