The extension for GoodLinks (both Firefox and Chrome versions) can't be activated. After clicking the icon, I'm directed to sign in with my Apple ID, but after doing so, I'm redirected to a page with the message "Authentication Error. This action could not be completed. Please close the window and try again."

Using the network tools on the Apple ID verification page, I see a 421 misdirected request to Cloudkit.

GoodLinks syncs data over iCloud. But I'm not having this problem with other extensions that are synced over iCloud, like AnyBox.

I've tried using a fresh profile with tracking prevention and content blockers off, and with Safari user agent, but still the same problem.

For what it's worth, I have iCloud's Advanced Data Protection enabled.

Apple ID verification should complete successfully so that GoodLinks extension can be activated
