Ratings on iPhone are not uploading to iTunes on PC
I have spent an extensive amount of time rating my music library in iTunes. Previously when I have sync'd my phone with iTunes the ratings have migrated automatically into iTunes. This is not the case at the moment. I have recently purchased a new PC and upon installing and opening iTunes, all of the previously existing ratings are now all gone (they were all there on my old Windows machine).
All of the ratings are still on my iPhone, but when I sync/backup it with my PC they do not upload.
When I view my iPhone in iTunes under the Music tab there is the checkbox to "sync music" in iTunes, but when I check it, it says "Are you sure you want to remove existing music... (bla, bla, bla) from this iPhone and sync with this iTunes library. Music, (bla, bla, bla), from other iTunes libraries will be removed and items will be synced from this iTunes library." I am reluctant to use this function since there are no ratings existing in my current iTunes library, I am concerned that this will erase countless hours of work rating my 90G library of music.
My questions:
- Will using the "sync music" function in iTunes described above remove all of my existing ratings on my iPhone?
- How do I fix this if the above is true? I want to transfer the ratings from my iPhone to my iTunes library.
Please DO NOT respond by saying that I need to "make sure I have the latest versions of iTunes and iOS installed" on my phone and PC. Both have the latest versions. I always update both immediately when new versions are released and check for new versions constantly. Currently running 12.12.9 on iTunes and iOS 16.6.
