My only real issue is that the app constantly glitches now at the point where you are setting your substitutions. Devs, please test and fix! It basically refreshes by itself & then that tab is gone. It used to refresh, but then it'd still be there (on next tab after "other stuff you may like") but lately it just disappears so you only get to set like 1 or 2 sub preferences. So then you have to communicate w/the shopper which doesn't always go well. This is my 102nd order, so I'm not new to this.
