Background data usage very high

[b20mgb]

Hello

I am a premium subscriber, using android.

I seem to be using a large amount of data, but never use the app unless on wifi (except for music already downloaded). From looking around, it could have been an app issue, so I uninstalled, and cleared the cache. 

Since Thursday 23/03 I have used 10.07mb (foreground) and 58.86mb (background). 

Does anyone have an ideas what is going on and how to stop it? I've been a member since March, so based on that have used a lot of data on what I believe to be nothing!

System is as follows.

Galaxy S6

App version 8.0.0.805 arm/V7

Android version 6.0.1

Thanks in advance!

Matthew
