I developed a PWA to send web push notifications, and a small number of users are testing it. (Add to home screen, then subscribe from the app)
It works fine on Android, but some iOS users noticed they stop receiving notifications after a period of inactivity. Only after they tap on the PWA icon, they keep receiving notifications (no need to re-subscribe)
I eliminated the invisible push limitation (which is 3), since my users received 50+ notifications before the restriction.
I already checked these links with no luck: Related issue for Firebase: https://github.com/firebase/firebase-js-sdk/issues/8010 Apple developer forum: https://developer.apple.com/forums/thread/728796?page=2
What are the restriction parameters? Time of inactivity, or number of notifications, or a combination of both?
How can I find the latest official information? Manually testing with multiple iOS devices isn't always feasible.
Thanks!
