First Sign In: Guest users cannot connect to sharepoint

Hi everyone,

 

I created a PowerApp in order to interact with guest users (who are already in the company's Azure AD tenant), but they are unable to connect to sharepoint at the first Sign in, even though they have a PowerApps plan and all sharepoint permissions they need. Everytime they try to sign in, they are asked to fix the sharepoint connection, because their Login credentials are displayed as {username}{token} (s. Image A) and if they try to fix it, they get messages like this:

 "An error occurred during authentication.

Session ID: d6dfbd00-721a-474b-a048-d3c40e18de5f" (s. Image B)

It seems to me that there have already been similar cases with this problem:

Do you have any suggestions on that?
Thank you!

PS: If you wan't to investigate further, you can take the Session ID from above to look at.

I don't think you can give permission to people out of tenant even if they have the plan.

Did you ever get to the bottom of this?

 

I have some users who can successfully connect, but others who are having a similar problem.
