I like the new Discourse PWA support for iOS. However, since I’ve been trialling it I’ve found myself inexplicably logged out a number of times (at least once a week). And oddly, if I force quit the app and re-enter, I am logged in again.
Same here on an iPhone 7, iOS 13.3.1
That is interesting. I have multiple sites, including Meta, on my iPad and the session on there was last used 3 days ago. After unlocking it the Meta pwa as still alive and logged in. It is running the last 13.5 beta iOS.
