Notifications work intermittently. I thought maybe it was my 2022 equinox(Wireless). So I tried it in my wife's Audi(wired), & does the same thing. Notification icon shows there is 1 there. I select it to be read and my cars screen goes off an on for about 2 min.(music still playing on Spotify). When the screen stops glitching, shows no new notifications, even though they are unread on my phone. Tried to reach Google but unsuccessful. Is there not a phone # for support. This is so frustrating!
