One more thought. This might be specific to the pwa on Android/Kiwi browser, but often a sideways swipe (intentional or not) closes the pwa, and reopening it resets you to the top of your feed.
If you've scrolled deep, this means it may take a while to find your place. I could be annoyed by this, but instead I've taken it as a sign, that maybe I need to either refocus on the present, or choose to do something other than nostr.
Just a little message from the cosmos telling me to piss off. I can take that gfy in stride.
