Getting notifications about new threads in "30 Days"

[GiveMeWordGames]

When I don't follow it, never followed it and don't want to? I've tried watching and then unwatching and am now out of ideas. Thanks!

This is very strange because I do follow 30 days and today I've got 2 notifications about new threads in 30 days. But when I click on the notifications and it takes me to the topic there are no new threads and the 2 notifications are not marked as read even though I've clicked on them and gone to the topic.
This is just as of this evening this is happening.
.

Oh, yes, that too. The notification stays even when I've clicked on it and the number of new threads is apparently rising exponentially!

Hi there @GiveMeWordGames . Thanks for getting in touch. Could you tell us whether you're getting email notifications or 'on site' notifications and what device and browser you are using (or if you'e using the app)? Thanks!

Yes thats exactly what's happening with me.

I just tried logging in on Chrome but it's still the same as on the Samsung Internet that I normally use: the 2 notifications about increasing number of new threads in 30 days are still showing as unread.

Hi. It's onsite notifications, I'm getting it using chrome on my Sony Xperia phone and chrome on a MacBook AND chrome on a PC.
