annoying red dot by "home" button

I am experiencing the same problem... and apparently so is this user:  Red dot on HOME menu - Zoom Community

I see a progress bar across the top of the screen that is only half-filled, but no idea on how to fill it.  See below:

I've pretty much tried everything, including clicking through every item on the Home tab, but nothing works 😕😕

If I ever figure it out, I'll come back here and post the solution.

Very annoying. I finally did find a link to email support at zoom. Their response is basically that this is just the design and they have no plans to change it. I advised them it's a terrible UX/UI design. No response. I hate customer support that is not supportive. Looking at other alternatives. Good luck to you!

Thanks @servicematters; you at least found a response.  To paraphrase their reply, "Oops! It's a bug, not a feature, but we don't think it's worth our time to fix it.  Tough it out, folks."  (Obviously not the fault of the person who won the lottery to reply to your message.  Glad I don't have that job!)

Try this on desktop: side menu > All (with the comment bubble icon) > click the funnel to the RIGHT located by the blue + > click Show Unread Only. Click through them.

If that doesn’t work then you should try clearing the Zoom App data and cookies:  click on your profile picture > settings > general > Zoom Apps (scroll all the way down) > clear local Zoom app data and cookies. Hope this helped! It did for me!
