Transcript on Zoom replay

[hlniner]

I give accent modification lessons via the Zoom link sent through Fiverr. I often replay these to take note of clients errors during sessions. In the past there's always been a transcript of session on the Right side so I can quickly move through the video. However the last 3 times there's no transcript. I contacted the Help people and the answer was an unsatisfactory "It is completely up to our system, and we do not have any kind of information on when there is going to be a transcript". Has any had any problems like this? My understanding of Zoom use outside of Fiverr is that transcript is an on/off thing, so why can't it always be on? Thanks for any information you can provide.
