Is it just me or do lemmy apps forget where you are if you switch apps on Android?

Apologies if this is the wrong place but I'm not sure where I should post.

If I have any lemmy app open to a particular thread (I mainly use Thunder but it happens on all apps I've tried) and I for e.g. switch to my email app for a couple of minutes, when I switch back to lemmy, it will go back to the home page. I'll then have to find the thread that I was on again. I have noticed this on Thunder, Connect, Voyager, Summit and Liftoff. It didn't seem to happen on Jerboa when I tested just now, though I'm sure it used to happen.

Is there something that app\lemmy developers have to fix or is it my crappy Samsung A10s?
