Keep the regional feature description visible
This article concerns HBO Max’s US sports help, not a promise of the same competition or feature in the UK. The US guide describes preset Multiview streams for competitions with simultaneous coverage. A displayed mosaic does not mean viewers can substitute any desired event into each panel; the guide says the presets cannot be changed.
Use the control for the actual screen
HBO Max says audio initially follows the top-left view. On computers and television devices, moving focus changes the audio to that view. On phones and tablets, viewers instead choose from the Audio and Subtitles menu. The guide also distinguishes mobile limitations: expanding a panel to full screen and Multiview captions are not available there. These are client-specific controls within the documented US feature.
Follow one game deliberately
For example, a US viewer watching two fixtures in a supported preset may hear the wrong commentary while assuming that touching a panel changed the sound. Inspect the actual audio control for the phone rather than copying television instructions. On a television, read the focus indication before selecting full screen, and use Back to return to the preset. Verify the event and commentary together. If captions or a custom event arrangement are essential, review the published limitations before relying on Multiview. Do not infer a UK event entitlement, a general multi-screen allowance or successful account playback from this published workflow.
