iPhone 13 - no sound

Hello.
I just got my new iPhone 13 and installed the Zwift app. There is no sound. The app works well but without sound.
All the other apps have sound.
With my former google pixel 4a, I had the sound.
I have checked the sound parameters and everything seems ok.
If somebody could help me.
Thank you.
Jean Michel

I have the Same Problem, does anyone knows why? And what is to do?
Thx Tom!

Hi @Thomas_Jindra I noticed your concern and wanted to see if I could help! Could you please double-check check you don’t have your iPhone on silent mode? Should be the little slide on the top left of your phone.

If the issue continues please try uninstalling and re-installing the app.

Ride On.

Solved. Many thanks
