I've observed the same with cold feet. It's even worse when passenger has the temp below 69 on the other side, apparently running heat and AC at the same time. Another annoyance is that the center vents are not on by default. Overall, heating has been disappointing but bearable.
Same. Only had my R1S a few weeks, but noticed this issue this morning for the first time. Nearly ran off the driveway because I was actively using the back up guide.
I went into the Spotify settings and changed the quality from Auto to High. (The settings page clearly wasn't optimized for the large display and the dropdown with options was oddly in the lower right corner.) If I recall, it didn't sound better at first, but did after choosing a new playlist.
