In the past hour, I tried sharing an app (that was successfully imported 1 day ago) with another user and got the top error in the image, and tried to import a second app which is the second error in the screenshot.
Is there something going on with Powerapps today? I have also been seeing errors of 'datasource may be invalid' for the past 6 or so hours in a separate tenancy in 2 different apps.
