Can't click "Subscriptions" because Multiple Admin Accounts Detected

Last night I updated to the final 2.2.6 and thought I'd click "Subscriptions". It immediately told me

So I followed the link to How to correct a Multi Admin error - Hubitat Documentation and removed my wife as an admin. I added her back as a guest user. (and this is my only hub)

But I still couldn't click Subscriptions as it was insisting I have multiple admins. 12 hours later it is still throwing that error message.

Have I not waited long enough? Is there something else?
