This just started occurring, I think with the most recent Mac update. When I try to open GoodTask on my Mac with Big Sur, I am receiving the following error:
“GoodTask.app” is damaged and can’t be opened. Delete “GoodTask.app” and download it again from the App Store.
Mac Version: macOS Big Sur 11.2.3
GoodTask Version: 6.5.5
I've tried removing the GoodTask app, downloading and reinstalling from the App Store but same result.
Update
Removing GoodTask, rebooting and then reinstalling appears to fix the issue.
