It has been reported in several forums that mobile app does not open few activities like Bigbluebutton, H5p and database. They all show: "template has some error and can not be displayed".
No one has ever responded properly. I have also opened github issue in one of the plugins...but still no use.
No one has responded here too. It is really annoying to use mobile app to access Moodle sites causing great inconvenience to teachers and students.
