It'll be down to your bank's rules. My main bank and brokerage work flawlessly, sync everyday. My secondary bank and Amex need to be reauthenticated every week or two. So I just update those once a month. Just go on simplefin and run the 2FA plus some waiting.

It doesn't sync non-bank stuff, so there's some RRSP providers I just enter manually.

For $20 cad a year its fine. I wouldn't use it to track daily expenses unless you know everything will work. I do all my finances once a month so its fine for me.
