The iOS app gets the device time zone wrong. My phone is (as automatically determined by the OS) in the Berlin time zone but the Clozemaster app assumes “Athens (2)”.
Since Athens is currently UTC+3 and Berlin is UTC+2 during summer time I’m assuming the app is looking at the current UTC offset only and then looking up the time zone based on that but disregarding DST.
This causes problems for me because every day between 23:00 and 0:00 hours, the app has the wrong idea about what’s ready for review and will present sentences for review before they’re due. It’ll also get the daily goal wrong.
