I downloaded the official Mobile App on my Android phone and tried to connect to our test Moodle server running Moodle 2.4.4 (Build: 20130513), but received the error message: Cannot connect: the site must use Moodle 2.4 or later.
I have already checked "Enable mobile web services" under Settings > Site administration > Plugins > Web services > Mobile and have double-checked that the mobile web services automatically enabled all the necessary services.
Any suggestions?
