scheduler is busted

I am so frustrated that there is not even a support email that is monitored. I tried the chatbot but it kept insisting I needed to log in when I am ALREADY LOGGED IN!! 

Anyway, I used Scheduler for weeks with no issues. Then all of a sudden I get an email from zoom saying I need to re-authenticate. So I do. Now all of a sudden, nothing works. Every day shows no availablity. I cant run my business this way, spending 2 hours trying to solve a problem I didnt create. Can anyone help?? Starting to think zoom is not the right tool for a small biz
