Music no longer syncing to iPhone!!

would a full phone reset back to factory settings and update from back up wound do the trick. Then delete all my music from my Mac and start my library from scratch and reload alphabet artists one by one work do you think? Major ball ache as it usually takes around 124 hours to Resync my music library. Or do you think this failure to sync will always be here until Apple do an update or two?

I’m going to see if I get the same result with my iPad later. If it works then the fault must be with the phone then? Also I’ll take a look to see if there is an issue with finder communicating with my phone. However it makes backups ok to my Mac, it just isn’t syncing the new music

Very odd now. My iPad syncs and I can move music manually over to it no problem whatsoever? Also backup completed normally as it does in my iPhone. Just iPhone isn’t syncing my music library? This is perplexing!

Did a reinstall of Big Sur after trying to see if a fresh plist file would work (didn’t). After doing that recurved a message saying that a small file needed to be download for my iPhone to communicate with music. Success I thought but nope that didn’t work. So still back at square one! Will be trying out a program to wipe junk files etc next. However to go from working one day and the next not working after hundreds of successful syncs is totally baffling!!!

Well today I found a solution albeit a complete stroke of luck! Got my phone out ready to wipe it and start again from scratch. I had my phone to automatically sync when connected. So it started to do this. However I had not plugged in my external HDD which contains all my music. I noticed the syncing circle was white and to my amazement the progress bar was saying it was syncing tracks, which it hasn’t done for days. I laughed at this as I openly exclaimed it would have trouble as the drive isn’t plugged in. I then plugged the drive into my MacBook. To my amazement it then flashed up it was going to sync 501 songs into my phone! It duly synced all the missing music onto my phone! I then tried to sync an album normally and the session failed to finish. But when I emulated the sane conditions the music synced. So there appears to be a bug of some kind somewhere which isn’t recognising something in there. I’m going to try unmounting and mounting to see if that works with the drive to save on physically having unplug and plug it back in. So there is a solution of sorts and I have no idea why it works but it’s does and my music is now fully synced again, twice!

Duplicated it twice now. However my music is in an external HDD. It’s obviously done form of bug in the OS. Will try again in the morning using the unmount and mount to save wear and tear on the physical port itself. I’ll post up how it goes

Well it worked a couple of tines I tried the same method and then missed my window and it took all the music off my phone! 🤣🤣🤣 so bit the bullet and erased my phone and started again from scratch. Wiped my Music library clean and deleted the musiclibrary file to start from fresh. Am now reloading my 7600+ albums back on peace meal as music can’t sync hundreds of thousands of songs at once. However it is syncing now with my phone with no trouble whatsoever, which has made me breath a sigh of relief! Just going to be a while to get my whole library back onto my phone. So I found two solutions! 🤣🤣👍🏼👍🏼👍🏼

Ticket raised. I’m really cheesed off as within 24 hours I now have a bricked phone! Would a redownload and install of BigSur help? Was much easier when it was just iTunes

Even if everything was working perfectly just 24hours previous to this?
