App navigation not loading when launching app

Some merchants are reporting that my app sometimes loads without the navigation (the one powered by App Bridge).

Even refreshing the page doesn’t work. Only a hard refresh brings it back.

Frustratingly, I can’t reproduce the issue myself. Anyone faced this before? If yes, what did you do to fix it?

I am on App Bridge 3.7.7, and the app is built in React.

Have you moved to the CDN hosted app bridge? That is the latest and recommended approach App Bridge
