After the recent UI change in the Seterra mobile app, when you are playing a map quiz and move the map around (as you need to for many of the map quizzes), it seems to think they you have guessed while moving the map around so when you click on the correct place it is yellow, orange or red rather than white. It seems to be intermittent and I think it happens more of you are also zoomed in. It is making the map quizzes with larger maps pretty much unplayable at the moment.
My whole family has encountered this on different phone - we are all on Android but different phones (e.g. I have a Pixel and my husband has a Samsung phone) so although it might be android related it doesn't seem to be connected to the model of phone.
I don't know how to how to do a screen recording on my phone - particularly as a screen recording won't show what I'm doing in terms of swiping, pressing etc. It's a bit intermittent but happens often enough that it shouldn't be too hard to hit if you play for a while on a map that requires panning and zooming (e.g. try Phillipines provinces or Russian oblasts)
