iPhone contacts not syncing to iCloud
I have ~250 contacts on my phone. About 150 of them are on my Mac/iCloud, but there are 100 on my phone that will not upload to iCloud. I have gone to groups and ensured that they say they are in iCloud, and all 250 of them are. I've also gone to settings to make sure that iCloud sync is on for contacts, and I've turned it on and off several times. Lastly, I tried resetting my phone to an iCloud backup- on the recommendation of a Senior Advisor- and even that didn't work. This is a long-standing issue. At one point, I upgraded my phone to an iPhone 13 Pro and the issue still didn't resolve. I really need my contacts to be synced for work, and it's driving me crazy that they're not.
