[Authentication Completed] then not logged in

Google Login succeeded in an account, a screen of Netdrive is while hardening.
notLoggedIn

Hi,

There was an issue with our backend system which causes OAuth logins. It’s fixed now.

Sorry for the inconvenience it caused.

Ahh, this is not fixed now. I just paid for the product and it is hanging at the same point, successfully logged in via Google, with the message Authentication Complete - You can close this window, and then it just spins in the NetDrive box.

Thank you very much.

Perhaps,
Because my computer is Japanese for the cause of the issue

And ,I’m sorry in English which isn’t accustomed also.

Of course.
The Window [the message Authentication Complete] is closed.

then Never stop spining Net Drive window
