I got a Philips Android TV about a month ago and connected it to my google account and everything works fine, but the Google Assistant on my TV is UK English, whereas all the settings on my phone for google assistant are set to English (US). It's not a super big deal but it is bothering me a little bit, because I have no idea how to change the language of the Google Assistant on my TV. Does anyone know how to change it or have a similar issue?
You have to change it using your phone:
Press and hold the home button on your phone or say "ok Google or hey Google" until the assistant appears, then say "open assistant settings", once there look for the language option, you can change it from there.
