Hey @Sirion,
Welcome back to the community and thanks for your post.
I'm sorry to hear of the issues that you're having with the TV GO app and for the late response to your message.
How are things working at the moment with the app? Has there been any improvement since your post?
Have you tried to remove the app from your device and re add it?
Do you get any error messages at all?
Regards
Steven_L
