The Chat Notification Badge That Won't Die

[NMSAZ]

I know there's another thread on this, but literally none of those solutions worked, so I'm a starting a new thread.

My chat notification won't go away. All of my chats are read. Here's everything I've done to fix this already (note- It's a corporate computer so I can't mess with the anti-virus):

• Signed out of the app every (desktop, web, phone)
• Restarted my computer
• Cleared the cache data from all 13 different locations
• Changed the setting to close the app when I shut down
• Closed it in the Task Manager
• Turned off all of my notifications 
• Clicked on every chat I've received over the last week

The only thing that seemed to maybe be the culprit was a very large company meeting and I was the last to leave. There was a lot of chat in that meeting, though I didn't participate in any of it. The reason I think this was when I went to log into to Teams from my browser, as I started to type "Microsoft Teams" I noticed in the suggested sites that there was a chat message from that meeting. So obviously I've left the meeting. I've deleted that chat. I've even left the teams channel that hosts those meetings. 

For what it's worth, I don't have any notifications on the phone app (android). It's just on the desktop and the web. 

Please, for the love of god, help. It's slowly driving me insane and I don't have the mental capacity to deal with anything else that makes me insane during quarantine. :) *jk- I'm fine. It's a joke*

Update: So I FINALLY cleared it. I don't know why, but I've always cleared all of my notifications and I didn't have this issue until recently, but out of sheer desperation, I decided to scroll through all my chats and found a "Who is" chat that was marked as unread from (April!!!). 

So I don't know why all of the sudden the chat from April suddenly because "unread", but I've never been happier to see a green checkmark at the bottom of my screen.

@NMSAZ the notification badge was stuck for me as well.

The way I found out what was the unread message:

• Go to Activity
• Filter the unread notifications
  
• Click each of the channel activities which are from the culprit channel

Strangely for me, only this thing worked, as it turned out that the unread message was a `@` mention and it was deleted. I even tried going to the top of the channel chat but you can "read" a deleted message :face_with_tears_of_joy:.

Thanks, had the same problem. It was so irritating to see the chat notification without any unread chat. I could not even find any unread chat in the activity filter. I had to actually scroll through every chat finally found the culprit. It was a team meeting that I did not attend around 2 months ago. Not sure why it suddenly got tagged as unread. I guess it's something that happened post the latest update.
