I set up a pro version allowing for 1000 participants. When joining by computer or iphone or tablet to zoom via username and password, I’m successful.

However, when trying to dial in by phone it says:

“This meeting does not allow phone dial in”.

Please, what am I supposed to do to allow?

 I went through the set up procedure with no success. 
Also, what number do I put in third party audio?

Username. Or both username and password, or neither?

Hello?

We have encountered some issues while using Zoom. We would like to inquire about the following issues:

1. Delay in audio between teachers and students.
2. Delay in displaying handwritten content between teachers and students.
3. Sudden switching of the whiteboard screen to the camera view.

We would like to confirm whether these issues are related to Zoom's platform. If so, could you please provide us with information regarding the cause and potential solutions?

When I finished my meeting I got an error message to say the recording failed to convert because a previous recording was still converting. I realised that I had forgotten to select a location for the recording of my previous meeting, so that dialogue box was still open.

The error message said I could go to meetings > recordings to manually convert the recording. But I can't find that. On the app, I can go to meetings > recordings, but it only shows a few old meetings.
