A couple of useful videos for anyone unfamiliar with Zoom, and how to improve it for music use: (not sure why the second one is so much longer, when there's actually less that you can do!!)
1. For PCs/Macs/laptops
Zoom for PCs etc
2. For iPads/tablets/phones:
Zoom for iPads/tablets/phones

And one other thing: best to install Zoom on your device, which you can do any time before the meeting starts: if you do that, then all you need to do is, at the appointed time, open the Zoom software,go to "Join a Meeting" and use the meeting number and password.
You don't need the long url if you do it that way: I know of several people who have failed to get in as they used the long url where they should have put the meeting number!

May see you later!
