We’ve been made aware of an issue with TV Go where you’re unable to watch on a device that has been registered even though it has been used before on PC or MacBook. This can cause all slots and changes for the month to be used. You’re currently allowed 5 devices with 3 changes per month.
This is caused when the cookies and cache for TV Go are removed / deleted. This is not a fault and is working as expected. To avoid the situation you simply need to change the settings on your browser to keep the cookies active for TV Go.
If you do need your devices reset then please let me know and I'll be happy to help.
