See attached screenshot:
The orange label is supposed to have text aligned in the center, which is not showing in beta-preview. (It does show in the Thunkable Live app.)
The blue button is supposed to have straight corners with borderRadii = 0 on the right, but this is not showing in beta-preview (and not in Thunkable Live either).
