There's a problem with Power Apps Studio right now. Please try again later

[zeedee11]

Failed to obtain authoring session token from RP. [InvalidAuthenticationResult] AuthenticationResult is not valid. Error: Safe cast for AuthenticationResult failed.

I tried clearing my browser cookies and history, tried a different browser. Still same issue.

I have 3 powerapps that are part of a solution. I have lots of flows within the solution as well. I normally navigate to my solution by going to PowerAutomate first, click on "Solutions" in the left side menu, open my solution, and then edit my flows and apps there.

When I try to edit or open any of the 3 apps within the solution via this method I get the error.

However, if I navigate to PowerApps first, click on "Solutions" in the left side menu, open my solution, and then edit my flows and apps there... I have no problem.

The last thing I did before this problem started was click on "Publish all Customizations" at the top of my solution while in PowerAutomate.

What happened?

It fixed itself on its own after about 5 days.

Same issue here but when launching a canvas app using the Launch function. It only happens in the PowerApps editor (not in the published app). Any insights?
