I’ve subscribed to the monthly Now TV deal, but can only stream on one device. As soon as another device tries to stream, it receives a message that I am already at maximum capacity! I am currently streaming the Lions match, but my son can’t watch it on his tablet.
What’s gone wrong?!
If you want to watch on more than 1 device then you’ll need to subscribe to Boost.
Unless you have boost you can only stream on one device at once. Now boost would allow you to stream on up to 3 devices at once. The five devices you're seeing are the devices that are in your device list. This would in effect be the last five devices you have used to access Now. Have a look at the two help article at the links below
Keep in mind that if you do sign up for boost. It can take up to 4 hours for the account changes to take effect unless you sign out the now app and sign back in again
I know much of this probably isn't you want to hear but at least you now know what's going on😀
