what did you do and what was happening? i only can imagine if you play on browser in private mode, that the “private” just deleted all files of the game on you phone
no i wasnt in private browser
i was playing web version when the game froze. after a while i got a notification saying an error occurred while trying to sync data and files, which led to me manually restarting my computer
after the restart i found out that due to the error all unsynced data and files have been deleted, including the website's data
