So glad you contacted me. My great techie keeps doing things that make it work, and then it doesn't. It failed again this morning. It's the first time in 20 years we've been connected that he is stumped so I hope you are a real smartie! What next?
This is what he said:
Can you try contacting zoom technical support? I'm out of ideas at this point other than "fiddle with random things and reboot the computer." Their tech support, especially if you have a paid account, will be much more likely at this point to come up with a permanent solution.
