The Walmart shopping app does this, too. With a cart full of upwards of 200 items, (we shop infrequently, so the list is big by the time we do), it infuriates the hell out of my spouse and I. I won't even get into how random and haphazard the items are ordered (and it's not due to the order we selected things).

Last month Apple released their developer keynote (WWDC26) where they acknowledged their search function doesn't work well. Obviously they were saying it now because they were releasing a fix but it was comical to hear them essentially say "have you ever searched in mail or finder for something you know is there, and search just can't find it, yeah that shit happens to all of us" lol
