My Question or Issue

I have 2 issues really. I have reinstalled twice from Google Play with no success. 

Issues 1: 

Ads will not play and the app has to sit for about 10 minutes before it continues with songs. It says that it is playing an add but nothing for a while. I have reinstalled on this issue twice to date. It can happen multiple times in an hour of play and if I restart the App it does nothing to help.

Issue 2: Recently the App has started to play ads in the middle of songs. It has happened twice today that I remember again fresh installs don't help.
