After the recent updates our notifications restarted and today they reached 11111. I had earlier written a post when the notifications had reached 33333.
You have to keep a vigil and take a print screen shot the moment it reaches the number you are looking for. Even a delay by a second you will miss that opportunity. It is already 11113 as I am completing this post.
It is not rocket science but it did give me some satisfaction.
Have you tried to keep a vigil on your notifications this way?
