A business user has built a SharePoint-backed canvas app that works in Studio, but the layout breaks on phones and tablets. The immediate consequence is user distrust: the app looks unfinished even when the data and form logic are working.
If you're unfamiliar with this industry, start here.
Canvas apps give makers control over screens and controls, but responsive behavior depends on display settings, containers, dynamic sizing, and testing across device sizes.

The Reality
Business professional asked to build an internal Power App

I start the morning feeling pretty good because the request tracker finally opens, shows the SharePoint list, and lets me submit a new item. In Power Apps Studio, the screen looks tidy enough. I send the link to two people for a quick check before the team meeting.
By mid-morning, one person sends back a phone screenshot where the buttons are half off the screen. Another says the form is usable on their laptop but awkward on a tablet. I try dragging controls around, then realise every quick fix seems to break a different screen size.
The small win is that the app still works: the data saves, the gallery loads, and the approval flow is not the issue. The painful part is that nobody judges the app by the hidden working bits. They judge it by the first broken screen they touch.
What I want is a simple way to rebuild the layout once, test it on the devices we actually use, and know what 'good enough to pilot' looks like before I send the next link.

You'll build: A repaired responsive screen plus a one-page device acceptance checklist.
You'll build: A completed mobile layout review checklist for one app.
We traced backward through five layers of "why" until we hit the source. Here's what's really driving this.
Why do users see a broken layout?
The app was arranged for the maker's current screen size rather than tested against the devices and browser sizes real users will use.
Why was it arranged for one screen size?
The builder used fixed X, Y, Width, and Height values or nested containers without a consistent responsive pattern.
Why did the builder not catch it earlier?
Previewing in Studio creates a false sense of completion unless the maker also tests phone, tablet, browser, portrait, landscape, and scroll states.
Why is responsive design hard for this avatar?
Power Apps containers have their own properties, parent references, wrapping, overflow, and child-control behavior, which is a UI system rather than a simple drag-and-drop surface.
Why does this persist across apps?
There is no lightweight release checklist that turns responsive layout from an artistic judgement into a repeatable maker workflow.
Root Cause
The visible failure is a broken mobile layout, but the root cause is an absent responsive layout workflow: device targets, container rules, dynamic sizing, scroll behavior, and acceptance tests are not defined before the app is shown to users.

The pattern they all miss — and how to beat it.
Most beginner materials teach how to add containers, but the paid pain sits in converting a nearly finished internal app into something that real phone and tablet users can actually use.
Teach a repair workflow anchored in the learner's own app, with clear pass/fail proof for device states.

Solution Strategy
A briefing can help diagnose layout readiness; a course is stronger because the learner must practise rebuilding and testing a real screen.
Start with an atomic course plus a downloadable device checklist.
