Android app release lag

[Pattseh]

I get that there is certain pressure due to Apple music to get iOS functions out as soon as possible, but why am I starting to feel that all andoid users are being left waiting due to this? 

Spotify has released a number functions, including Running, on iOS a good two months ago already and their dates are still TBA on the Android app.
Now I am aware of the beta version for android that does have the functions (I wasn't fast enough to join the beta, of course), but that isn't much comfort for a paying customer having the negative side effect of preferrential prioritisation(?).

Can spotify at least give a small peace of mind and announce the release date of the functions so I can consider if it's worth paying full price for only a portion of the full service?
