Most annoying for me is when I tap to open a note and read its comments. When I tap the back button to go back to the home feed, it 'forgets' that post's location in the home feed and sends me back to the top of the page, effectively making my home feed only fit for reading the most recently posted notes.
This is something I've experienced on virtually every alternative social (both native app and PWA), regardless of client, seems to happen more often on mobile. Only real workaround I've found is to basically use Nostr in 'stalker mode', visiting each follow's profile page directly to see their notes.
