Prosites problem with upgrading a site (new install)

I have Pro Sites setup on a brand new install (about the fifth time installing it, I am getting pretty good)... lol

I am using the Stripe gateway... I have upgraded my Stripe keys and re-added those into my Pro Sites settings.

Whenever I try to "upgrade" an account from the Free Trial I get this message:

"There are pending changes to your account. This message will disappear once these pending changes are completed."

I am not sure what this means nor will my end users... what does this mean?

I have recorded a video where I walked through all this:

Thanks for your insight on that message...
