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.
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.
