I loaded an app via TestFlight which handles a Siri Intent. Siri only responds with, "Sorry, I'll need a few more minutes to process the updated app." and gives me a button to open the app. When the app was loaded via Xcode, everything worked as expected. Any clue why this would still be happening after downloading the app about 15 hours ago? Everything appears to be alright in iTunes Connect and the dev portal.
Thank you!
