Hello, are you still have a problem with this? I have been having issues with my iPhone Pro 11 and Catalina for weeks. Sync taking forever after minor changes, putting duplicates on my phone etc. Thanks.
Yes still having some issues. I quit using/syncing iCloud on iPhone for awhile which helped stop the computer from constantly analyzing from phone changes (still does way too much with any other changes - Add 10 megs of screen prints with only words from phone using airdrop and it will analyze and write 300MB to 1GB of data & fix one date and/or location nearly get same) but definitely stopped changes to people albums that were already correct and lessened the rest since iPhone didn’t have iCloud turned on.
I got everything right on computer with originals downloaded. Started trying betas and eventuality retried to turn on iCloud photos on iPhone after first removing all photos from phone to download correct versions from iCloud it started over. Maybe not as bad, but while phone doing it’s thing for 3 weeks loosing some labels on people already done on computer and even incorrectly labeled some. Computer started reanalyzing photos and writing & reading gigabytes of data most days until iPhone got done scanning all photos (but still in process for weeks). It then improved some, but still happened when phone gave me pics of people to review or spent enough time curating pics. Coincidence or not phone’s people finally finished with recent beta, but numbers still don’t match computer and still have found some errors on phone and a few more labels Switched to unnamed on computer from correct person’s name.
So It’s getting better, but it still is bad for me and still seems like the devices battle each other and retrigger over-analyzing. I don’t see why full Photos syncing between computer and iCloud correctly needed 3 weeks of scanning & analyzing by iPhone when iCloud photo turned back on. This time iPhone had zero photos and downloaded all from correct iCloud and computer sync, but seemingly still spent 3 weeks redoing scanning and analyzing of pictures itself. If I update something on computer or add a face to a pic during this it will show on iPhone, but it doesn’t seem to want to show same respect to existing work done by computer. I also think even some of these get changed as phone get to them during analyzing process.
Then there are completely different issues like rotating pic causing names to disappear as they don’t rotate at first (not sure why some times it corrects itself and other times stays unnamed). Sorting is limited. Adding photos to a shared folder puts them out of date order with no way to quickly sort correctly (guessing its differing upload times getting them out of order). Folders still disappearing on computer. Can’t share a memory video using computer like on phone without redoing it as slide show. It also seems to guess that photos without a location but taken close together with ones that have it over the years are in same location, and includes it in a memory. Correcting it triggers photo analysis and all the other processes.
Curation and scanning for memories and faces have really added nothing for me & maybe been a negative (the memories I used are ones made from albums I make or from expanded people albums showing more than curated summaries). Most times i switch to all photos to find photo i like the best. If it had just accepted & respected existing info and face names that have been input for over a decade I would have been better off.
