Amazon app using Whole Foods on iPad

I can browse the aisles (at least the first few items displayed in each main aisle), but the search function doesn’t work in the app on my iPad. For example, it says “No results for sugar in Whole Foods Market. Try checking your spelling or use more general terms”. The same search in the app on my iPhone works though.

what happens when you try 

same thing is happening to me too no idea why
