I have been playing on computer for the whole times I've played geogussr and this is the first time I have encountered this problem. When I do the daily challenge or a community map (haven't tried classic), my name would not appear on the leaderboard as it usually does and my friend said that my name disappeared off his map. This same friend said he had this issue too a few months ago. I hope you can fix it soon because this is one of my favourite games.
