iPad codec issue

Have been watching a series on my Apple TV. Downloaded the remaining episodes to my iPad so that I could watch whilst travelling.
When I tried to play I got an error message on the pad that said that the codec was not supported for this type of media.
I checked the app to make sure it was up to date. I have an infuse pro account. The series works on my Apple TV so not sure why it wouldn’t on my iPad.
Thanks

Could you run one of the videos that aren’t playing through mediainfo and post the results here?

Just to make sure we have all the bases covered, what model iPad (and model number) and what version number iPadOS, and finally, what version number of Infuse?

There could be a codec incompatibly issue so @james or one of the iPad users may be able to help narrow down the problem.

If you are able to post the iPad model that would be helpful. Some older devices will not be able to support Dolby Vision content.
