Music Control Issues with 2.8... No more control ?!

Hello,

I never had issues which were not "cured" by a reset of the phone, the watch or both or my previous Fenix and the Instinct.

But these times I'm stuck even after a factory reset on the Instinct...

I'm on 2.80 (the last version today)
My phone is a Samsung S8 with the security of jan 2019 (last one)
I use the last versions of Poweramp or Neutron or Pocket Casts.

The only control I can get on those three applications is the volume but on Neutron which I can stop and sometimes (after many attempts) change track...

Am I the only one ?

Is this an issue of 2.8 ?
