Our site is using the default moodle.net messaging server and is registered. We're running Moodle 2.9.3 and the latest version of the local_mobile plugin. At some point, mobile notifications stop being delivered to all our devices. I've tested this more personally with my Android phone and my iPad using forum. I requested a new Airnotifier access key manually (because the automatic request method failed) to see if the new key would help but it hasn't.
Any suggestions on what I should do next to trouble shoot this? Thanks.
