I'm trying to figure out why mobile push notifications aren't working. We're running a registered Moodle 3.2.3+ (Build: 20170519). We were successful in configuring the messaging server (messages.moodle.net) -- we successfully requested an access key, and that is included in the messaging configuration. Notifications are enabled on the site. The users who are testing have their notifications enabled properly. Their mobile devices (e.g., iPhone) are running the latest Moodle Mobile app. They successfully added the site, and made sure the app was set to receive notifications (both in the iPhone settings and the app settings). But when we submit forum posts, for example, no push notifications are received on the phone for those who should get them. I can go to the app and see that there are new forum posts in the notifications, but these notifications are being pushed to the phone. No alerts, etc.
Is there anything else we should look at? How do I know that the messaging service (messages.moodle.net) is actually working for this site? Is there a way to test/ping this? I can't seem to find any troubleshooting information.
Thanks... Brian
