Just finished two hour call with senior advisor at AppleCare. TLDR: if it doesn’t appear at all, it’s apparently some installation bug; recommend rebooting, both watch and phone. If it appears BUT shows just message “music will appear here, blah blah blah“ (WHICH IS WHAT WAS HAPPENING TO ME.), turns out this is supposedly a feature, not a bug.
Longer story: I was experiencing the same issue with iPhone 15 and watch 9 do not disturb. Already had restarted the phone and watch, and in fact, wiped them both to factory settings and set up as new device, and saw no change with problem. The advisor, after running lots of diagnostics, screen sharing, etc., was about to escalate to engineering, but decided to try things out on his own watch. Saw exactly the same issue. On the basis of that testing, plus the fact that in the complications list under “now playing“ the only option is that weird “suggestions“ thing,he decided that this is an actual change to how the complication functions. He said something about it’s now operating more like a widget, so you have to actually press it to open up the NowPlaying app to see what’s now playing. I’ve never bothered with widgets on the watch, so I have no idea what he meant by that, but I told him that in any eventI that was a really stupid change, and he told me to put in feedback.
Moreover, we discovered that if you load some music onto your watch and play it from the watch, the complication still will not show what’s actually playing while it’s playing (like that stupid message in the complication says), but the complications appearance will change to show instead of that message, little pictures of album covers with your three most recently played songs. You still have to click on the complication to open the actual nail playing app to see what’s playing, but the message about “music will appear here…“ no longer appears.
Anyhow, I’m still convinced that this is a a design bug, where Apple was trying to add a complication under now playing for “suggestions,” but in the process deleted the regular now playing complication that shows what’s now playing the most useful part of the complication).
Apologies for any weird typos or bizarre structure. I can’t see much, so I’m dictating, and you know all about AutoCorrect…
