I wanted to configure Create Advanced App Clip Experiences which is not available on App store connect. As per WWDC
we tried uploading the binary to the testflight to configure app clip but the build failed with below error
App Store Connect Operation Error
"ERROR ITMS-90834: "Unsupported content. This app contains an app clip. Apps with app clips cannot be submitted at this time."
Let us know way to test app clip feature with Advanced App Clip Experiences
Also let us know the size limitation for app clip
