Why is my published app on Google Play Store refusing to open

Hello there,
Please i publish my mobile app using median.co as a website tp mobile app converter. My mobile app on the Google Play Store has been reviewed and published on the store. However, when a user opens the mobile application to run on their mobile device, the application opens a link (https://us-central1-gonative-demos.cloudfunctions.net/splash) on the browser and the mobile app crashes and refuses to open.

Please, i am writing to know why this is happening and what are the steps to resolve the issue. Thank you for your assistance in advance and i look forward to a response.
