We are having the same issue on 3 of our websites.

At one point, it tells us magically that the domain is not connected to the saved key and secured from UNACMS.

Nice to see everyone still jumps on the bandwagon of it's got to be a you problem, not a UNACMS issue.

Also, not a good look for an organisation that charges a lot for their software and hosting, when they can not provide a stable App Store. Maybe too much interconnectivity.
