This started almost exactly two hours ago, and on a day like this when I'm already getting hundreds of notifications, it is extremely annoying to get them all twice!
Thanks for confirming that it's not some issue with my internet provider or something.
However, it seems to have stopped for me a little over half an hour ago, except for one double post a few minutes ago.
EDIT: The "double post a few minutes ago" was actually duplicated in the thread as well, so disregard that.
This bug is back again, since an hour or two.
Happening to me too.
