Dear Customer.
I am contacting you from Sky regarding an problem you reported to us with Sky Go on your Android device.
We have a test build available that we believe should fix this for you and would like to invite you to use this.
In order for this to take place can we ask that you reply to this email with your Playstore email address and we will send on further instructions on how to download the App.
This can be found by clicking on the Playstore Icon then the 3 lines at the top left of the screen. The email address shown is the one we need.
Kind regards
