Sorry for the late reply and for the frustrating experience you've had.
We're getting this looked into from our end. In the meantime, please power down all registered devices for 5 - 10 minutes before trying again.
Apologies for any inconvenience this has caused.

Thanks for your messages.
I have two Now TV boxes, a chromecast and a desktop pc on my account. I was able to sign into all devices and watch Now TV fine as long as only using one device at a time. As soon as I wanted to watch two devices, the second one received the concurrency error message. I tried all combinations of devices, and it didn't matter what two devices I tried to use, one of them would not work. I have had the same four devices on my account for some time, but only last week tried watching two at a time (my son wanted to watch Karl Pilkington!).
As I had not received a solution on here I went on the live chat and explained the problem. The operator removed all the devices and then I added them back again. I tried watching the Chomecast and one of the Now TV boxes and they both worked, so it seems to have sorted it out. I asked the operator why it happened and his explanation was that "Sometimes the system goes funny." 🙂
So, fingers crossed, it seems to be sorted.
Thank you for your help.
I have read all the previous posts and I have exactly the same problem. 4 devices registered but I can only use one at a time for the last week or so - I should be able to use 2. I am using 2 iPads, a NOW TV box and Apple TV.
When is is the problem getting fixed? I'm thinking of cancelling my monthly membership if I can only watch on one device and I'm sure I am not alone.
any updates please?
Sorry for the late reply and for the problems you've experienced.
We're aware of an issue at the moment where this is happening when you're watching on 2 devices and one crashes, or loses power or internet connection. If you then try to watch on a different device within 4 hours of this happening, the system will still think you're still viewing on the other device.
To fix this, go back and start watching again on the device that lost connection, then immediately close it down. You should then be able to watch on the new device.
Our tech team is looking into this issue at the moment and we hope to resolve the problem shortly.

This error has been happening since the recent update. Got 3 boxes on account and today just me in house using one box and got this error again. CS removed all boxes. I added two and all was fine but error returns on 3rd box even when other two boxes disconnected. Seems like adding more than two boxes is causing this error. Is technical team aware of this?
