Problems with the stream

Buffering & Quality 

You need at least an internet plan of 5Mbps for one stream. For 3 streams, the minimum recommendation is 24Mbps. If you have a large household that takes advantage of other streaming services, make sure your plan will support them or you may see buffering and quality issues.

Streaming Math:

8Mbps X number devices = required estimated bandwidth

Heads Up: If you have other streaming services, some streams require between 5 to 15Mbps for HD quality.

3 Streams

You can watch 3 streams concurrently. This means only 3 people can watch HBOMAX at one time. You may receive an error that too many streams are in use.
