Iphone app problems after core infinity upgrade

[Wdw]

Good afternoon,
 
I have received my Experts pro after core infinity upgrade, all seems fine so far.
 
BUT, the iphone app doesn't work properly any more .
 
I cannot control volume any more , only switch off

Does anyone can confirm this or do I something wrong ?

With original remote control everything seems fine.

similar experience here...the app can turn on the D and the volume dial will show a change made in volume, numbers rising or falling, but the true volume at the D remains the same
