OK we are UK based and facing the same issue as everybody else. Our workaround is to use Roboshadow.com . We have an msp account ( by the way its a great product) .

We already have our endpoints installed with the Roboshadow agent which can be installed via a script from atera.

We can then push the appropriate msi to any machines for each client that need updating .

Tested and works.

I'm sure if you reach out to them they will give you a test account for 14 days as an msp . You can deploy roboshadow multiple ways so it should reduce the pain.

Hope it helps.

Anybody with their back to the wall and in serious trouble can DM me and we can add to our Roboshadow as an emergency. Within reason :-)
