When I put my iPhone down for a bit and come back to Voyager, the app resets back to the top of the feed. I then have to scroll so far down to find the place I was at.
My iPhone settings does not show Voyager app in the background app refresh settings.
I believe this setting would keep the feed in the same place when I bring the app back.
It also happens just locking the phone and coming back, even with no other apps open.
Do you have any other resource hogs running in the background? Perhaps a poorly-coded VoIP or VPN extension could do that.
If you have access to a Mac you can use Console.app to see what log events there are about Voyager when you switch away. That would explain why it’s being killed.
