Unread message icon

I'm currently posting this with TornTools enabled.

I tried with it disabled and it's the same.

theres an unread message icon that shows even though all read.

I pressed mark all as red, it goes, but then comes back when I change page.

I went back to chat 2.0, it's still there

I opened and closed every chat box and it won't go away.

Looks like you're on chat 2.0. Try switching to chat 3.0 and see if you can find the message. You can switch back to 2.0 for now if you do not like 3.0, but likely no action will be taken by devs as chat 2.0 is going the way of the dodo.

It says "return to chat 2.0" I have tried both and it appears on both

my mistake, i only looked at the first screenshot and thought the icons were 2.0 ones. Just to confirm, did you scroll all the way down in the list of chats? 

This happened to me yesterday but Mark all as read fixed it after a few tries

I tried around 10 times, I will persevere and post tomorrow if it persists

It seems to have fixed itself like you said.
