showLoadingIndicator is no longer showing an indicator for our app. #2860
Description
We've recently observed that the loading spinner—which previously appeared when launching the app—is no longer visible.
In our Teams app manifest, we have "showLoadingIndicator": true, and we explicitly call app.notifyAppLoaded() and app.notifySuccess() upon successful initialization to dismiss the loading screen.
While the app still shows a blank splash screen during loading (which persists until notifySuccess() is triggered), the expected spinner is missing. To verify this, I temporarily removed the notifySuccess() call, and as expected, the blank splash screen remained indefinitely—but without any loading animation.
So the loading state is technically working, but the spinner itself is no longer being rendered.
Our current manifest looks like:

I've tried downgrading the manifest version to 1.13 and updating teams-js from 2.32.0 -> 2.40.0, I've also tried removing every single optional section from our manifest leaving only the static home tab. Everything I've tried so far has had any effect.
