C&C Rivals no sound on ipad

My sound stopped working on the game three days ago.   I have tried the following to attempt to fix:

1. Update ipad to latest version.

2. Delete game and reinstall

3. Checked other apps (Spotify, Netflix, Browser(Safari), other games) all have sound.

4. Yes volume is turned up in the game.

5. Yes the Music & Sound FX is check on in the game settings.

6. I go not have a manual mute/silent button on this ipad.

7. I’ve rebooted the ipad several times.

Its got to be something in the game update.  Please advise.
