Notification working but not sending updates

I recently installed OMV 5 and after a few struggles got everything set up and working I think, however one of the last things I did was set up notifications. I put in my email credentials, sent and received a test email several times, but I have not gotten any notifications for things like software updates or the usual Snapraid messages. The test emails still work so I'm at a bit of a loss why none of the notifications seem to be working, any ideas?

I’m not looking at it right now so I can’t be exact, but there is a settings tab in Notifications where you can select which kinds of notifications you want to receive.

I have them all checked already, that was the first thing I checked.

I had it backwards: The Settings tab is where you set it up, and Notifications is where you choose which emails to receive. Do you have the "Enable" button green in Settings?

Yes I do. The test email works perfectly over and over, but updates that have been available for days and snapraid notifications just aren't being sent.

I wish I could help but I have already exhausted my "vast" storehouse of knowledge. Hopefully someone will be able to point you to the solution. Someone is always saying "Clear your browser's cache" but I don't know if that would be applicable in this situation. Maybe restart your server. Got a large hammer?

No problem, my vast storehouse is really a cardboard box with a side missing. I imagine there might be a command or something i can run to trigger it and then check the logs to see why nothing happened, but I don't know what that might be so I come here, generally works out after a little bit of fussing around I find.

Still hoping for some help if anyone has any clue what might be wrong. Right now after enabling and disabling notifications, it appears to work for snapraid and system load alert messages, but still doesn't notify for software updates.
