Did you know the notification system is about fixed ? Just click on your notifications and then scroll down to "More notifications." Keep doing that and you will eventually get most if not all of them out. . Work in progress. 

Thank you for your effort!

Yup. That worked. You are amazing !!

Awesome! Glad to see that fixes are being rolled out.  Thanks for the update.

Thank you so much! Thank you!!

Thank you!!

I just checked mine. It' was up to 690. I scrolled through my notifications and it went to 663 and then it stopped and wouldn't show any more notifications. I'll try again later and see if I can get more off. It's good to know its being worked on. Thanks Rooster :)

Brilliant! It ought to be possible to "thank" a question.

NICE!! My notifications are down to 0 zero, as in none!!!
