Starting a scheduled meeting now switches from web portal to desktop and shows guests invalid ID

[rba]

For a few years now I have used the Web portal, which I like, to start reoccurring scheduled meetings. Since the update, I click start in the web portal and it looks like it's going to start the meeting as usual, but instead it takes me to the Desktop app and I have to pick the guest again and click start again. Meanwhile, my guests are trying to log in using the reoccurring link and get an invalid ID message. I don't want to use the Desktop app, I like to do everything from the Web portal, and I sure don't like having to "start the meeting" twice. How do I fix this? Thank you.
