What this means
The Pro UI keeps the site state understandable by surfacing non-fatal notices and returning you to the license tab after each action.
Common states
Invalid token format
Inactive or expired license
Seat limit reached
Temporary verification outage with grace mode
Recommended action
For invalid, expired, inactive, or seat-limit responses, fix the account-side condition first and then revalidate.
For temporary outages, confirm whether the site is in grace mode and retry later instead of disconnecting immediately.
