MonsterInsights encountered an error loading your report data There is an issue

Hello,

We work in multisite, and we have added Monsteringht to all our sites.
Your plugin is awesome!
However, we have back office connection errors.

Indeed, we have to integrate the UA code in connection with email address, everything works correctly.
Except that the back office is disconnecting all the time and we have this error:
MonsterInsights encountered an error loading your report data There is an issue with your Google Account authentication. Please use the button below to fix it by re-authenticating.

Yet the UA tracking code is present, but we have to reconnect each time.
This is not possible on all of our clients’ sites.

Do you have a solution ?
Why is disconnection happening?

Thanks a lot for your help.

Regards
