Here's one for you. Both of us are using V1.0.2.
HoneyDew seems to be automatically deleting items. For example, she puts milk on the list. When she sends a sync, mine responds with a sync message deleting milk from her list (and mine). It happens in the reverse as well. I put milk on the list and sync and get a response from her deleting it from the list. I'm guessing it is a problem where we have had milk on the list previously and later deleted it. Now it perpetually considers milk to be bought even if we want to add it back onto the list.
That's a pretty big bug!
