Had Pixel 6 phone in December of last year and was overjoyed to work it. I was able to use Google's handy assistant when i needed to and was impressed with functionality. However in January my phone prompted me with a System Update and without hesitation i proceeded to let it do this. Afterwards when the update finished and had restarted the phone i noticed Google Assistant wasn't picking up my voice. I checked settings and the Assistant was on. I even tried to re-train it. I had no luck since.
