Updraft error message: "Google Drive: Account is not authorized."

I got that message too after I’ve done the authentication with Google.
But that message was displayed with another error message explained in this page:

I did the Short-cut,
but the backup progress didn’t finish.
So I read the rest….

First, I did the manual reload every 5 minutes,
still no success.
Perhaps, my last reload exceeded 5 minutes.

Second, I signed up with a facility.
Easycron Free has the minimum interval of 10 minutes:

But Pingdom Free can do it every minute! So I tried it.
Yes, my first backup to Google Drive succeeded!

And you know, the error message has dissapeared!
What a relief ??
