Whenever I stream on my phone and then close to stream on TV ( through Firestick ) it gives error code for exceedng devices - even if I have logged out of the account on the phone. is this a commn problem?
What do you mean logging out on your phone?
See when you stop streaming do you exit the stream then closing the app?
If I recall switching devices can take up to 5-10 minutes. Unless you have boost then your not restricted to 1 stream, but you also benefit no ads with on demand content and other handy features.
You were recently watching on a different device
When you stop watching on your first device, make sure you exit the show or movie you were watching rather than just pressing pause, turning off the TV or closing the app. This will signal that the stream has ended.
If you don't do this, you might need to wait up to 10 minutes before you can start watching on another device.
And if you do do it, the switch to another device can be practically instant.
