VerticalScrollArrangement content does not appear on device

Hello, I think I may have found a problem in MIT App Inventor. I moved all my components inside a VerticalScrollArrangement, but on the phone nothing appears, even though in Designer I can see the components. I tested with screenshots from Designer and device. Could you please check whether this is a bug or a layout issue?

Is your VerticalScrollArrangement set to true?

yes, but nothing appears on the device

Could you share your project with us so we can take a look at it?

chios.aia (3.0 MB)

Works just fine here.

so, is it my device that is causing the issue and not displaying it?

It might be, try setting the Screen Scrollable to false and see what happens..

I tried setting Screen1 Scrollable to false, but it still does not work. I am using an iPhone — could that be related? About two weeks ago everything was displaying normally without any issue

Try this

chios (1).aia (79.4 KB)

  • reduced image size significantly
  • switched to device default theme
  • fiddled about with sizings of components

I imported the .aia file you sent and tested it on my iPhone, but it still does not display correctly. So could this be an iPhone/Companion issue?

Could be, can't help with that, android only here.

If it works on another device, then it may not be a bug in VerticalScrollArrangement. It could be related to Companion version, screen sizing settings, or layout height/width configuration. You may want to check if Height and Width are set to Fill Parent and also try updating the Companion app.

We have a beta version in review to address part of this problem. A more complex fix needs to be explored.
