I set a facebook ads campaign with the subscription link provided by zoom webinars, now, suddenly it stopped working and people can not subscribe from the link that 15 days ago was working properly.

The last time i launched a webinar, happened quite the same, when i started the webinar, my susbscribers could´nt conect, they said that , when they pressed the "join webinar" button from the confirmation e.mail sent by zoom, there just show the message "waiting till host start this webinar", but it has already started

i have not changed the suscription link , could somebody explain me why is this happening?

I recently put the Umbutu OS on my lenovo laptop and now my Virtual Bacground wont work, also All I get when Zooming is Black screen and no one can see me.. Is it Zoom or my operation system? Do I need to download a new Zoom app?  Or what can I do to fix this?

Hello, I am having challenges whenever I launched zoom. I have good network but whenever I launched, the connecting will on and never connect to the audio. The video movement is very slow. I have uninstall and install several time but still I am having the issue? Any support
