Native tabs on iOS 26 ignore background colour props
ExpoLikely fix
Expo SDK 57, expo-router 57.0.24, iOS 26
There is no error message for this one, only the symptom in the title.
Cause
On iOS 26 the system tab bar is Liquid Glass and takes its colour from the content behind it.
Fix
Do not fight it; use the JS Tabs if you need a custom-coloured bar.
