I am not showing up in the waiting room. Support has been unhelpful for months.

Does anyone have a similar problem, what should I do?😭 Every now and then, when I connect to a conference without a specified start time, I am not visible in the waiting room (and if at that moment I create my own conference, no one is visible in the waiting room). Everything is fine with my device (connecting from another device also does not work), the Internet is great, the application is updated to the latest version (and I also tried deleting it and downloading it again), Windows, BIOS, drivers, etc. are also updated to the latest version. I even created a second account - nothing helps in instantly resolving the situation. The support service does not help me at all, they write monotonous advice and nothing helps!😡
