I have a mobile application, which was working correctly before the update 3.18041.20, now when the application starts it does not load the screens and does not allow to add new screens or any other element.
The last release version of powerapps for this application was 2.0.750, the application is still productive, however it is not possible to modify it either on the web or in powerapps studio.

Thank you for reporting this! The session ID has been especially helpful with our investigation so far, so thank you for providing that, as well. We've reported the issue and will fix it in an upcoming release.
