Resolved: TWA App not working fullscreen when downloaded from Play Store

To hide the address bar in a TWA app, you must have setup and asset links file on our server with valid SHA certificate fingerprint. Sometimes the app works fine when we test it by directly installing through apk, but address bar is shown when we download the app from play store.

The reason for this is that when we upload an app to the play store, Google sign the APK with its own signing key which changes the SHA certificate fingerprint.

So, to solve this issue, we need to add both the SHA certificate fingerprints in the asset links file so that our app works fine whether we install it directly or through play store.
