I haven’t been able to replicate this since it only happens when I get a notification on the platform so I don’t know what is really going on but I’m gonna try to explain the issue.
I had this happen twice. The first time the notification message fell into an infinite loop by itself. It wouldn’t stop ringing and piling up on the lower right corner of the screen so I had to block all notifications from the site to stop it. On a second occasion, it would just pop up again each time I clicked on it.
I’m not very familiar with Chrome notifications, so I don’t know if I’m doing something wrong but I think this might be worth checking.
