Volume Control for Amazon Music..IPhone

I feel like an idiot asking this…
I can’t figure out how to control the volume while using Amazon Music Unlimited on my iPhone. We just switched from iTunes to the the new Amazon Limited and have noticed a significant improvement in the audio quality connected through our Cambridge 851N. Through iTunes and my iPhone I could control the volume…can’t figure out how to do the same on the Amazon App. Really don’t want to add Alexa, but if that is the only way to control volume will consider it.

Thanks

Try the volume buttons on the left side of the phone. I don’t have amazon music so just a guess.

Thanks…Hoping that there is something in the app itself so when I switch to other uses with the phone, the volume isn’t messed with.

One of these kind souls with knowledge of the app should chime in soon.
