I tested on Firefox and Chrome on Android. It works on Firefox, not on Chrome. This is the same when directly navigating to the search URL e.g https://foma95.netlify.app/search/ghr. It won’t load movies on Chrome Android, but will load them on everything else. This is possibly (thinking through my fingers here) because you are navigating to /search/{search-term} rather than returning the search results to the page.
Do note too that the API Key for the The Movie DB is clearly visible in the client-side JS of your app. If you would like to keep this private (and other keys in the future) you would best move this into a serverless function
