With regards to notification issues reported by some users
Some users have reported issues with the notification (in the browser) over the last 48 hours. In fact there are two separate issues:
1) some users reported gettting an error message. We hope to have solved this issue now. If it occurs again please report it in the comments.
2) slow loading of the notification drop down (10-15 seconds). We are currently not sure what causes this for some users only. This is being investigated, so please bear with us.
Have a nice morning/day/evening
