I have a zoom account I paid for. I used it yesterday. Today I could not use my app. When I tried to sign in, it said I was using a device from a place I had never used before ( the same computer and network I used yesterday), so they sent me a verification code. I entered that and got the message that I needed to update my app and should contact my IT manager. But I am in my own home, I am not a company, and I have no IT manager (of course). So I called support. In order to get support they wanted some Zoom id number which, of course, is inside the app I cannot open or update. With twenty years of software development and system support behind me, I can say this is the most user hostile support I have ever seen. Can anyone out there help?
