As a Forum member, I can no longer delete 'spent' notifications. This seems to be slowing down the download speed for any new notifications selected, to the extent that I have to leave the site entirely. There used to be, until about a week ago, a 'clear notifications' button and I would say that life on the site was better then, despite suffering from slow download for reading selected posts.

 

Help or comments would be appreciated.

There are many add-ons disabled because of the slowness of the Forum and this is one of them (same as the App Access which is also disabled).
