There is a "refresh" button next to account balance - anyone that didn't think to try it when looking at the wallet really seems to not be trying all that hard. Idiosyncratic, yes. Bug, no I don't think so. Somehow the rest of us have been dealing with it for many months now.
you think nobody thought to press refresh button

, be serious. Balance only became visible after pressing withdrawal for 0.001.
Correct. The sync behind the refresh button was overloaded and not working. It works now, but it was not operating correctly while under load.
