What is Native Portrait support?
Native portrait support allows you to use a player's settings to automatically rotate any portrait content, removing the need for any rotation before you publish your content.
Not all players have this capability, so be sure to check the ‘Supported features and Contents’ articles for your players in advance of trying to use the feature.
How do I use Native Portrait on my Player?
Once you have confirmed support, you can see how to activate Native Portrait mode on each Player type within it’s dedicated Help Centre section.
