strange issue - removeusersfromall groups

[baha00]

I am using connect to exchange via secureapp model.

Connect-ExchangeOnline -CertificateFilePath "C:\temp\mycert.pfx" -CertificatePassword (ConvertTo-SecureString -String "somepass" -AsPlainText -Force) -AppID $app_id -Organization "myorg.something"

Azure app has role exchange admin added, but removing from o365 groups doesn't work, drops out exception:

System.Management.Automation.RemoteException: Failed to retrieve executing user. Please try again later.

It removes user from security Groups without any errors

Some of the Unified Group cmdlets are not fully supported for CBA, and it's sure taking a lot of time for Microsoft to fix them. I'll update the script to use direct Graph queries eventually, until then connect via the "regular" method.
