Hey there,

We have been aware that something wrong goes with the purchase from MacOS recently. The devs are still working on it, here is a half-solution that might help.

Could you please uninstall the app > open "Terminal.app", copy the following code, click Enter, and then re-download the TickTick.app:

pkill -f TickTick
defaults delete com.TickTick.task.mac
defaults delete 75TY9UT8AY.com.TickTick.task.mac
rm -rf ~/Library/Group\ Containers/com.TickTick.task.mac
rm -rf ~/Library/Group\ Containers/75TY9UT8AY.com.TickTick.task.mac
killall -u $USER cfprefsd


After that, could you please go to the premium page in TickTick, scroll down to the bottom and tap the "restore" button, check if it is activated?
