I've come across something quite weird.
We've enabled notifications (notification provider, notification hub, notification center) on SAP and notifications are correctly generated. Some people can see them others cannot. The URL at hand is this:
We've entered this URL in an incognito window in Google Chrome in let's say 10 computers, we've used the same USER and same PASSWORD, and in 7 of these computers we see the full list of notifications whilst in the remaining 3 computers we see only 1 notification.
I honestly don't understand what the problem could be because the URL is identical, same user, same password, no cookies, no session reuse.
Can you offer any help?
