Answer 1

Had an similar issue try manually starting on ionViewDidEnter and stoping it on ionViewDidEnter.
But first remove your loop, and autoplay properties from the options like so:
option = {
slidesPerView: 1,
spaceBetween: 10,
centeredSlides: true,
speed:1000
}
Then handle start and stop like this:
ionViewDidEnter(){
this.slide.startAutoplay();
}
ionViewDidLeave(){
this.slide.stopAutoplay();
}
EDIT:
If you want to make it work between tabs, then use the autoplay option like so:
option = {
slidesPerView: 1,
spaceBetween: 10,
centeredSlides: true,
speed:1000,
autoplay: {
delay: 1000,
disableOnInteraction: false
}
}
