Rebuild Android app with app.tripswithai.com as the App Links domain The Android App Links domain is baked into the APK/AAB at build time. From the screenshot, I can see Google Play Console is reporting that the domain trips-with-ai-travel-the-world.ba... (your Base44 default URL) is failing domain checks. To fix this properly, you would need to regenerate your Google Play files with app.tripswithai.com as the target domain. This is done from your app editor: Go to Publish → Mobile app tab → Build Store Files → Create Google Play files However, changing the App Links domain in the build itself is a Base44 platform capability — if the build tool doesn't let you specify a custom domain, that's a platform limitation I cannot change from support. 2. Route /.well-known/assetlinks.json to a backend function This is the core issue causing "1 domain not verified" in Google Play Console. The assetlinks.json file must be served at exactly https://app.tripswithai.com/.well-known/assetlinks.json with the correct content and Content-Type: application/json . Base44's routing infrastructure controls how /.well-known/ paths are served. This is a platform-level routing change that I cannot make from the support side.
