We like it, but were having some issues (new)

Weve been using the full version of this app for a very long time. Its had its little hiccups, but now the lack of sync is making the app, for our purposes, pretty much useless.
We fill most of our grocery list(s) via our iPad. But when we get to the store to fulfill our shopping, the list wont update on either of our iPhones.
Should have used a piece of paper, or well look for a better syncing app.
