I have same issue: ok google hotword is not working...tried changing language (i'm italian )resetting watch and also phone...downgrading google app, setting all authorization on...nothing worked...can someone help?
Had the same problem. Deleting cache and data of Google app on the watch worked for me. OK google finally works, but I cannot send WhatsApp messages via ok Google. After a reset it's possible but only for a few hours. Strange.
