iCloud won't sync notes on MacBook Air
This is the 3rd place I've tried to ask a question. They truly erect as many gratuitous, time-consuming, frustrating barriers as possible to getting what you need.
I broke down and paid for iCloud+ because Notes on my 2023 MacBook Air was only showing 1 after I took my MBA into the shop, when I have 165. My phone still shows 165, but my MBA still just shows one. I've changed my password, waited an hour because the device was in a "new" place (my apartment, where it's lived for 2 years), made sure both devices are logged into the same iCloud account (as if I'd pay for more!), and quit and restarted Notes several times. I've made sure syncing for Notes is turned on both on my phone and MBA. I can't figure out why it's not working or find any solutions, other than Apple repeatedly pointing me back to the same places like logging into iCloud (which it wouldn't let me do, even though I click "Allow" on the other device, where it gives me a 2FA code there's nowhere to enter).
This is ridiculously difficult and frustrating. Please help. Thanks.
