Music ratings added on iPhone aren't synced to iTunes library

Thanks SnickZ,

I have since done the IOS 14.5 to 14.6 upgrade, and the iTunes was already at the last available 12.8. Most of the sync is taking place, so the sync instructions weren't applicable, but I read through them line-by-line in my troubleshooting, just to make sure I wasn't missing a step in the new IOS.

iTunes is doing the full sync with other systems running antique IOS versions.

In my experimenting over the past week, I have determined that if I connect the iPhone to the Mac Mini directly using the cable, then the ratings information is transferred back to update iTunes. However, when I stick the iPhone on the charger and automatically sync via WiFi, songs are rotated and last played is updated, but ratings made on the iPhone don't get imported to the iTunes.

So I have a kludge to get the information uploaded - always open the case (the dust proof / water proof seals aren't going to hold up to daily opening) and plug into the Mac before putting it back in the case and on the MagSafe charger for the night.

Am I wrong to think "it should just work" on WiFi too?

Thanks barberlives123,

The phone is visible in iTunes over WiFi, so that article about how to setup WiFi sync doesn't seem to apply.

There is no error, so no message to check; we already did the updates; I can't imagine which security settings might need to change; and it's been restarted dozens of times.

The ONLY part of sync that does not happen via WiFi (that I've found) is transferring song rating changes from the iPhone to iTunes. (changes made in iTunes do get into the phone)

Finally started behaving after installing IOS 14.7.1 (released yesterday). Not on the list of issues it fixes, but it fixed it.
