I’ve seen this on the Android app (I’m on 1.36.8 (628)), but never the website.
Sometimes if I scroll too quickly while looking at my obs (I’ve almost never used this app to browse obs more generally, so I dunno if it it happens elsewhere), the wrong cover pictures for my obs will be displayed. Scrolling again and doing so more gently usually fixes the problem. Sometimes I have to restart the app.
There’s a second bug that happens if I swipe left or right while editing observations. If I go to edit an observation, and I set a taxon ID from there, and then I swipe left/right, and edit the next observation and set a taxon ID, then when I accept these observations the taxon IDs will not show as their proper IDs. Like, let’s say I picked “Angiospermae / flowering plants”, the result will be that the ID shows “flowering plants” as if I’d just written those words manually as a custom placeholder ID rather than chosen an established taxon. My workaround is to edit only one observation at a time, i.e. accepting the changes to one before going to another observation. Anyway I don’t know if this second bug is related to the first one, but just posting it here in case it is.
