Zoom web portal bugs

Hi, 

I have a paid zoom account with 500 participants. Whenever I change settings in the zoom web portal it doesn't get updated on the app. For example, I have turned on allow participants to join before host function from the web portal. So whenever I schedule a new meeting automatically it should turn on under the advanced options in the schedule menu. It shows as its turned on but when actually a participant try to join he cannot literally join the meeting before host. Every time I have to turn the option off and on in the app while scheduling to make it work. The same problem persists for numerous settings in the zoom web portal like, 

1. Mute upon entry 

2. Allow participants to join before host 

3. HD video 

4. Annotation settings etc.

 

Any suggestions? 

Thanks in advance!
