I've noticed this since I updated my Oneplus 5t to Oreo, when I connect to the radio in my car via Bluetooth, the controls no longer function. Music plays fine, but anytime I want to change the track I have to go to my phone.
I've tried force stopping, re-enabling permissions, and doing a fresh install of the app, but nothing has solved it. Other apps, such as Google Play Music work fine.
Is there any solution to this? Or am I going to have to resort to downgrading to nougat?
