A Row with repeating icons (for example stars) which I want to align left or right horizontally displays correctly in Composer Pro but the icons don't align correctly in the preview app on iOS, Android or Web.
The first image below show the Container Layout Alignment Settings, note this is set to Horizontal, Align Left in Composer Pro.
The second image shows the appearance in Composer Pro on the Left and how it displays in iOS on the right.
