I think, this causes becoz of web API and web APIs sometimes only work on phone(s) not on web, So, That might cause a problem and let your app crash and even I have a self experience on it. ---

once check the status of web API an if it says http request and something related to that, it means you can only preview on a phone, ok? ---
