I am not getting any messages/notifications (M/N) both on Facebook.com and Messenger.com both in Firefox and Chrome. I need to manually refresh the page to see if there are any new M/N present, which is very annoying.
It is worth noting that everything works fine in the Facebook and Messenger apps on my Android phone.
As I have said, I have tried two different browsers and it behaves the same in each of them. I have tried to check the developer's console for any errors, but I haven't found any. I have also checked the HTTP requests the pages do after loading. There are some happening periodically, however none bring up the new M/N. I have also tried to report the problem using the form on the Messenger.com website, but as expected, I haven't got any response.
Any ideas how to troubleshoot this further?
