Video pauses on ipad using external screen

Hi
I am having an issue where any video I play pauses when using my iPad with an external screen, the audio keeps going by the image freezes until I turn the iPad screen back on. If the iPad screen is on the video plays fine on the external screen. I have tested with other apps eg Disney+, and they continue to play the video on the external screen when the ipad screen is off. So it would seem its a local issue with Infuse.

I would be grateful if you could offer any assistance with this.

I am using an iPad Pro (12.9-inch) (3rd generation)
OS: 15.4.1
Infuse Pro 7.3.9 (4074)
Original Apple USBC AV Connector

Thanks,
Mandip
