I am brand new to YNAB, just got it on 8/21, so I am still learning. I downloaded it to my computer, then put the app on both mine and my husband's iPhones on 8/21. We have the same iTunes account, and we have only one Dropbox account (just downloaded on 8/21 as well when dowloading YNAB).
This morning I downloaded YNAB onto my husbands computer and was showing him some of the basics. I changed the budgeted amount for 1 category in August on my husband's computer (actually deleted the amount since we will not be spending it in August) and the change showed up immediately on my iPhone but not on my husband's. (We are at the office so I won't know whether my computer updated until tonight). So have I done something wrong? My husbands phone doesnt seem to be syncing, and when I looked up for a solution on the website what I found suggested that it is linking to the wrong dropbox account, but we only have 1, which I downloaded at the same time as YNAB.
