The menu is deep and has tons of options. The UI of the app sometimes gets in the way and leads to errors. Also, the experience in the app varies quite a bit from the web experience, which can be even glitchier. Also, the app behaves differently depending on the store I'm ordering from. Sometimes, the app won't let me order for immediate pickup. I can only assume that different stores have ways to throttle traffic originating on the app. You get no warning that ASAP ordering isn't available

App works fine, but the UI and overall experience could use polish. I submitted a pickup order and assumed it went through, only to find out later it didn’t process until I woke my phone back up—by then, I was already at the café. Not ideal when you’re in a hurry. Needs better feedback and background processing.

Removing items from the cart/basket if its not ordered immediately is a nuisance. I can't use the 'order later' option because I generally don't know when that'll be, so I add everything to the cart so it'll be ready to go once I am. Except I just tried to do that and the cart was empty, so now I get to waste time doing everything again. Awesome! Yes, there could be issues with availability or timing etc, but that's what warning popups are for. Don't just toss the whole thing out the window.
