Over-The-Air Wireless Distribution FAQ

Q: How do users install the iOS app directly on iPhone/iPad?
Users open Safari on their iOS device, scan the generated QR code or open the OTA distribution link, and tap Direct Install. iOS Safari recognizes the itms-services:// manifest link and prompts the native OS installer.
Q: Why does iOS say "Unable to Download App"?
This occurs if the target device UDID is not included in the embedded Ad-Hoc provisioning profile, or if the distribution certificate has expired or been revoked. You can resign your build using SignNext Studio before uploading.
Q: How long are OTA links valid?
OTA distribution links remain valid for 6 hours. After 6 hours, files are permanently deleted from Cloudflare R2 vaults.
