Thread:Project:Support desk/Watchlist and Ping not working all the time

I work mostly on Commons and the English and Swedish Wikipedia and my main user page is at Commons Goran_tek-en.

I do work as graphic and thereby different Requests on the Graphic_Lab pages of the wikis. I'm very depending on that I get a notification when someone edits a Request I'm working on or Pings me to get my attention.

My problem is that even though I have checked the box Watch this page or someone Pings me I don't get a notification all the time. Most often NOT.

When I look at my Watchlist I can see pages that I haven't got a notification on email as my Preferences says. Ping doesn't either give me notification by email most of the time.

To be sure to reach me please use my user page at Commons as above.
 * Is this a problem that is known or has it to do with something with my account/preferences?
