React Native Expo App Missing Status Bar in TestFlight - ios

Question

After building the standalone iOS native binary using Expo, uploading to Testflight and running it on an iPhone, the status bar looks like there are many elements missing.
What might be the cause of this? How can we fix it? Thanks!
In iPhone Expo Client:
Status bar looks normal.
In TestFlight:
Status bar appears to be empty except for the green battery indicator
