Just wanted to share that I just updated to 2021.4.15 on my 13 P85 with MCU2 infotainment upgrade and it fixed the YouTube/Google sign in security “glitch”. Hope it fixes it for anyone else too that was having troubles signing in!
try to log in on tesla browser to RuneScape . com game with your google login and after, you should be able to login to YT.I just checked in the YouTube app and I concur with BioSci above. Login still rejected from insecure browser.
I also checked album art for USB drive audio, and that is still not working at all. No album art. :-(
You got me all excited, so I ran out and tried to sign in. It didn't let me so I tried the brake pedal reset and tried again, nope. No workyI would like to note that I immediately did the scroll button w brake pedal reset right after the update completed and went straight to the YouTube app for login and it worked for me. Sorry it didn’t work for you guys. Try a reboot if you haven’t already.
