After a previous discussion here, I had to reconnect the GitHub app to get the import functionality working again. It does work now but, after the reconnection, all previously imported components now seem to be disassociated with the GitHub app, resulting in the app wanting to import every single GitHub repository again.
So now it seems we can re-import all components again and manually reconfigure the new ones before deleting the old ones. That's quite a lot of work. Or we continuously check each component manually to see if it's already been imported. Again, over time, a lot of work.
Is there a third option, where we can mark a repository as already imported so that it won't be listed as pending?
