Why does using Amex stop you using YNAB? Syncs fine for me.
Maybe I was spoiled with near instant syncing on my debit card, I used to categorize the gas i just paid for before leaving the lot.
But again, at 15 a month, that’s a lot of effort for a gui on top of a spreadsheet.
The benefit for me was quick transaction logging and categorizing, then a weekly/monthly check up. But with sync issues, those check ups became categorizing sessions, and just took too much time.
