zoom app schedular is blank page

I am a zoom pro user. If i try to schedule a meeting by click schedule button, it pop up blank page. Not scheduling input field. If i click scheduler tab, it is blank.

I have unstilled, reinstalled, sign out, sign in. It is really frustrating experience, take too much time. My time worth more than the subscription fee I paied. 

Last time, I have to schedule on web but launch on app have some problem, as you still need to open app's schedule page.

Please NOTE, this is a basic app, nothing to do with video, audio, device stuff yet.

And this community post system is ridiculous, when you post a discussion. you have to  put a topic. "This board requires at least on label for each message". What are these concepts of Subject, Topics and Label?
