I was at a location that offered free WiFi but was unable to complete the registration. This meant that the phone thought it was connected to the Internet via WiFi but wasn't really.
I forgot to turn off wifi and tried to use the YNAB app.
The app crashed after entering a transaction and continued to do so each time I launched it. Turning off wifi so the phone could use 3G cured the problem. I sent the report when given the option.
