I don't know if anyone else is having the same problem but when I tap the x to close a notification it doesn't disappear untill I refresh the page. I have this problem on pc and mobile (I thought it was my mouse at first). I didnt know where to put this so I figured non wam.

Having the same issue here

Might be better in the 'Development Group' ?

Contacted Messmaster about it the other day, I guess it will get sorted when it sorts

the x button to delete does not work my notifications either,

But there is a workaround...just go to the left margin area and you can mass delete all notifications, and that works just fine.

Appears to be fixed, at least on my end. Thanks MM!

Yes, it's back to normal again

Not sure if this is related, but when I click on the link to the notification about a liked comment, it does not take me to the liked comment. It takes me to a random spot on the same page as the comment.
