HI, 

I found this thread in the community

https://community.zoom.com/t5/Meetings/Revert-to-Old-Version-of-Zoom/m-p/91097

They talk about a URL: https://zoom-us-zoom.en.uptodown.com/windows/versions

Is this URL officially supported by Zoom? Can I safely download the older Versions?

I would have expected that the official Zoom Support would take care of this matter. Very disappointing that they don't seem to care
