I've noticed a few times now that the Android app states it must do a "full download" of the budget. The error message was cut-off in the notification pulldown, but it stated something about it being read-only. All I've been doing is entering two transactions, one immediately after the other. The first one syncs, but the second one still says its pending and then I see the error message stating a full download of the budget is required. I'm on my data connection (not Wifi) when this happens.
