Is that when trying to update or downloading the game completely new? If you can't update, please delete the app and download it again, if you canÄt download the app, please contact our support, maybe add a screenshot if you can, so that we can investigate the issue.
I cant speak for android, but for linux PC it is somtimes necesary to restart the computer before updating.
Same thing for uninstalling, it doesnt necesary take full effect until you restart the computer.
Presumably something somwhere is still in memory and preventing an owerwrite.
The reinstall did not work, but the reboot seems to have gotten the patcher to work; it's decompressing right now. Lost two days of calendar over this which means the monthly item is gone. No point in even logging in now.
