trouble watching recording

[medevents]

Hello I am hosting video on zoom and each time I share the recording through the parameters "only allowed people/email address specified can watch". But I have some people that have been complaining they cannot watch the recording . here is the message they receive when they try to watch it :" the video was interrupted dur to a corruption issue or because the video uses features not supported by your browser".

But in fact , the video recording is not corrupted because it does work for most of the group.

And someone told me  after receiving the message he tried to switch browser to watch the video but did not work either. What must be done to watch the video recording?
