Dislikes of YNAB 3 (solved in YNAB 4):
Syncing between devices, cumbersome in 3, still waiting to see in 4 (yes, I'm pointing my fingers at YOU, Apple!)
Lack of search function across accounts
I have reverted back to YNAB 3. Took a bit of time because I had to copy my changes from YNAB 4 back over to YNAB 3, but I did it. The major sticking point with YNAB 4 is that I can only sync desktop computers and my wife's android phone. With YNAB 3, I can sync everything using Dropbox and Wifi syncing. I had already been recording my transactions at point of sale. Can't do that with YNAB 4 and sync due to issues with the dictatorship called Apple. In other words, YNAB 4 is not functional for my family.
I am looking forward to going back to YNAB 4 despite some of my dislikes. However, can't do that until syncing is restored.
Oh, and WHAT is up with YNAB 4 preventing me from storing my local file to Dropbox? Really? It is a folder on my computer like any other. This is a major FAIL point for anyone wanting to do local syncing. Worked just fine in YNAB 3. Why the restriction with YNAB 4?
