Users kicked out and not able to join again

From past 2 days our users are facing a common issue. Some users are not able to join the meeting and some users are kicked out of meeting and if they tried to join again, they cannot join. 
@Allowing participants/panelists to rejoin – Zoom Support
referring to the above link I checked the "Allow removed participants to rejoin", and then created a meeting and  tried the same, I left the meeting and tried to join again but I couldn't join. 
I am using a Scheduled meeting.

I am able to join if I use the Join URL of the registrants and open it in a browser, But if I am joining using the mobile app, I am not able to join.
