Zoom's support is truly world class. And I'm not sure if that's because my company was an early adopter, but nonetheless, they're very helpful. If we encounter some kind of bug (a rare event), it's not long before the engineering team gets back to me with a fix. If I want to submit a feature request, a rep gets back to me instantly saying that it's now on their scope (and then it gets added to the product shortly after). If I have a question about some feature, Zoom support always has a speedy answer.
They're very good at giving detailed release notes any time there's an update, and their documentation is always great.
