Love that I can sync to other devices

This app works so well for my husband and I to add to a shared list and then either of us can shop at any time. It also keeps us from backtracking in the store. My one complaint is that it constantly syncs, and when syncing, the screen goes black and I cant continue what I was doing until the sync has completed. Please fix this bug!!
