Hi,
Sorry to hijack the post, but I have the same issues with my ipad (Safari, Chrome and Edge), videos starting with audio works well with other website. Only GT videos start on mute which makes useless my Ipad ☹ï¸
The article (Thanks Jarkko) is not applicable for ios since I cannot find the same options.

Please GT fix this issue and release the app update for ipad.
I have ios 14
Yamaha Pacifica 112v and APX600
