After most recent app update, I had a strange thing happen, and and now the app will not load at all.
MacOS, Big Sur.
When I tried to run Goodtask, I got a popup that I needed to login to the App Store, because the app was purchased under a different ID. This is not accurate, it's a single user computer, and I'm the only appleID tied to this iMac.
Then After logging in, I get a popup that says the app is damaged and must be removed and re-installed. I did that, no change.
