AppTesters certificates are intended for compatible iPhone and iPad devices using supported Apple signing and provisioning methods. Compatibility depends on more than the certificate alone.
The device model, iOS or iPadOS version, signing application, provisioning profile, app entitlements, and the IPA itself can all affect whether an app installs and runs correctly.
If you are updating iOS or iPadOS
Before installing a major or beta operating-system update:
- Back up important app data.
- Confirm that your signing tool supports the new version.
- Check whether the specific IPA supports that operating-system version.
- Keep access to your original IPA and current certificate information in case the app needs to be signed again.
An operating-system update does not automatically mean that the certificate has been revoked. If all signed apps stop opening, check the certificate and provisioning status. If only one app fails, investigate that IPA's compatibility first.
Can future compatibility be guaranteed?
No. Apple controls its operating systems, developer-account rules, certificate validity, and device-registration systems. AppTesters cannot promise support for every future Apple release or every device/app combination before it is available and tested.
For the most reliable answer, check the current AppTesters instructions or contact support with your device model, operating-system version, signing tool, and the app you are trying to install.
