When trying to run Printing/Scanning Apps created using Google Drive or OneDrive templates with the Russian UI enabled on the MFP leads to an error -- see attachment. When changing the language (at the SAME MFP) UI to English or Ukrainian, everything works well.
Translation of the error message from Russian:
The service you are trying to use may be temporarily unavailable. If this error occurs again, close the application and try again later.
Checked on an App made from scratch. The problem is still not solved.
