When I start the iPad Moodle app, version 3.6.1, on my iPad Pro to link to
it gives me an error "Error connecting to server". When I click "OK", I see the main menu page, but no link to my dashboard to enable me to access my courses. Up to about 2 weeks ago I was getting the connection error message, but still seeing my dashboard link. If I use the search button and search for a course code, I can access the courses, so there is not an issue with access permissions. The site adminstrator assures me that no recent changes have been made to the installation.
I have tried deleting the Moodle iPad app and reinstalling, but the same issue is still present. Rebooting the iPad also makes no difference.
If I use the "Moodle Classic" app, it warns me that I should be using the new version, but connects me without any problems, including access to the course overview page where I can see my courses.
