Chromecast 3 won’t play some files

My Chromecast won’t play certain files anymore…it will play about three seconds of the file, and then stop. This happens whether I am streaming from my iPhone or iPad. I am running the latest version of Infuse 7 on iOS 15.

The files in question are all playable on the Chromecast, and cast just fine from VLC Player for iOS. Other files play just fine. They used to cast just fine using Infuse until recently. I’m not sure what the issue is.

Can somebody help?
