iCloud contacts won't sync across devices and the cloud
This issues has been existing for me for months, as well as one of my friend. Whenever I create a new contact on my phone, it won't upload to iCloud therefore when I message that contact, to my other devices it is just an unknown number. My other devices also won't sync to iCloud. I ask the community this because I just bought a new iPad Air few days ago, and when I set everything up and open messages, its full of just numbers and emails, and when I open contacts, it is empty. I called apple support, I was on the phone for an hour toggling switches on and off and finally got 49 of my contacts appear (I have 160) on my new iPad and I tried to wait the other ones out thinking it will sync on itself soon but that hasn't happened yet. This is really making me upset and I would like to find an answer on how I can resolve this issue, because software updates are not working, and apple support is also wondering why lol.
I did notice something weird if that helps, when I sign into icloud.com on my phone, there is no contacts option, I cannot view my iCloud contacts using the web on my phone. The only device that is syncing with my iCloud contacts is my MacBook. My phone which was bought in China is also signed into my iCloud, sometimes features aren't available to me or doesn't work well because of that but I highly doubt it is that case.
iPad Air, iPadOS 18
