Please get this to the appropriate folks at Huel HQ, thought you might want some free UX feedback.
Using safari on iPhone 7, UK site
Use Case 1, Finding subscription options
Logging into site and finding “my account” was easy but one very small point for the my account page: it shows an order history at the top of the page, and at first I mistook this page for order history so dismissed it without scrolling. Even so, as my order history grows longer it’s a pain to have to scroll through to get to my subscriptions etc. I would prefer to see subscription options at the top and order history underneath.
Use case 2, managing delivery frequency
All fine.
Use case 3, managing delivery flavours
Unfortunately managing delivery flavours is difficult on my device as the user form is pushed to the right by the image (of Huel bottle, scoop, and pouch), and even with landscape orientation of my screen the fields are partially pushed off the right edge of the screen. I still got it to work, but then when I hit submit there was no page refresh or otherwise any indication my response had been submitted so I had to refresh it myself to convince myself the change had been made successfully.
All very minor UI stuff, keep up the good work!
