Why have my Messenger notifications stopped working?

[Windows Central Question]

My Facebook Messenger notifications have stopped working. I have uninstalled the Messenger app, turned off notifications in the Health app and turned them back on, rebooted everything, etc. I'm am really ticked off. I originally gave up Windows Phone because I was having problems with Skype. Since Messenger came onto the scene, I bought the Lumia 640 and the Band 2. For a while, everything was peachy, and now this.

I am running stock Windows Phone (not Windows Mobile)

If Microsoft doesn't fix these types of problems by the time the 950 XL comes out, I'm outta here. I'm tired of this crap

There can be many causes to that issue, including but not limited to: faulty network connection to having many apps running in the background.

Debugging the issue would require more than one exchange of replies, hence creating a Windows Central account is recommended in order to respond in this thread.

In addition to reinstalling the app and rebooting your phone, have you tried using a different Internet connection? Also, what was the relevance of the Health app to your Messenger app? Have you checked for updates to your phone?

My sister's Lumia 535 (older and lower-spec-ed than the Lumia 640) has been receiving Messenger notifications over our home Wi-Fi without problems. On the other hand, my Lumia 1020 is having problems once in a while with Messenger over cellular data (especially in areas where network coverage isn't the best).

My notifications have been acting funky lately too...but it's different, I do receive notifications, but hours late! I will try removing some background apps and see if it helps..
