I have invited one TestFlight user from iTunes to test my app. The app is currently under review status. When that user tried to install the app, at the time of launching in iTunes, it throws the following error :

Could not install XXXX. The app couldn't be installed because the developer's certificate is no longer valid. To resolve the issue, contact the developer.

Anyone can provide brief explanation what could be the reason for this and how it can be resolved.

I encountered this error because the build was signed using a provisioning profile whose certificate had been revoked.

When i checked in the developer center, the provisioning profile was marked as "Invalid".

I just clicked "Edit", selected the new developer certificate and regenerated the provisioning profile. When the new build was uploaded on testflight signed with the new provisioning profile, the error went away.

However, i do think Apple should be checking if the provisioning profile is still valid rather than developers finding it out after build is already approved by TestFlight and testers complain about this error.
