How many devices can stream HBO Max at once?
HBO Max allows 3 concurrent streams and up to 30 registered devices per account. If you exceed 3 simultaneous streams, you'll see Error 905.
Why does HBO Max say too many devices when I'm only using one?
Other devices may still show as active streams even when paused or minimized. Apps running in the background or devices that didn't properly sign out can count toward your limit.
Does signing out of HBO Max delete my watchlist?
No, your watchlist, viewing history, and account preferences are saved to your HBO Max account. Signing out only disconnects that specific device.
Can I remove all devices from my HBO Max account at once?
Yes, in your account settings on HBOMax.com, look for an option to 'Sign out of all devices' or contact customer support to reset all device connections simultaneously.
