Onn playback errors

Onn 2K device Andriod 14

Onn keeps giving unable to decode error when playing back recordings.

When the same recording is played back on another device no issues.

Yes, I have Uninstaller and reinstalled the tablo app several times.

Yes I have restarted the router

Yes, I have rebooted the tablo several times

I was not getting this issue with an earlier version of the tablo app. Is there anywhere I can download an earlier version of the andriod tv tablo app?(can only find the mobile app).

Any other ideas?
