Not able to assign users group to PowerApps environment.

[van.lam]

We used to be able to assign users group to PowerApps environment, but not anymore - we got the error below.  Is there any reason why this is happening?

We are having the same issue. It seems Office 365 groups are no longer available in PowerApps for sharing. Indeed we get the error: xxxx isn't in your organization's directory.

When will Powerapps support Office 365 Groups?
