Please tell us how to recreate the issue in as much detail as possible.

The best approach would be to get your code running in the NativeScript Playground and share the link with us, along with any additional details or steps to reproduce needed for examining the issue there.

Using angular NativeScript setting the textTransform to none has no effect on the tab's title text and still shows all uppercase as per default.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

All the below ways seem to not work

<StackLayout *tabItem="{textTransform: 'none', title: 'Favourites', iconSource: ios ? 'res://heart' : '', cssClasses: ['tabItem']}">

TabViewItem, .tabItem, tabItem {
text-transform: none;
}
