I also sometimes experience that issue, check in developer console if you don’t have errors with websocket connections. Not sure what causing that (my side/server side), but most of the time CTRL+F5 (refresh with clearing cache) fixes the issue
I’m not new to fediverse, but i found the same friction points like with mastodon
I do also feel like it is more jittery (android 13, jerboa 0.0.35)
