Fairly straight forward question. Does anyone happen to know if Google Play App Signing supports Instant Apps? The reason I ask:
Enter your app’s signing config, or select a keystore file. While it’s possible to use a debug config or keystore during testing, the generated Digital Asset Links file won’t be compatible with the release version of your app. If you do upload a Digital Asset Links file that uses a debug config or keystore, then before publishing your app you’ll need to generate and upload a new Digital Asset Links that uses your app’s release key.
From Blog post:- How to Create an Instant App Feature
If this claim is true, does the play console provide a means for generating a assetlinks.json? This is the file that you must host on the domain you are claiming to be affiliated with.

Yes, Google Play App Signing supports Instant Apps. You will use your Signing key instead of the Upload key because Google Play will re-sign your app with the signing key.
Android Studio provides a way to generate the assetlinks.json, just go to Tools > App Links Assistant > Associate Website, then you can select the correct keystore file.
- Add Android App Links > Associate your app with your website
You can also manually do it through the Statement List Generator and Tester
