I've an app running for some time in the Appstore now. Recently I had to renew my singing certficicates to be able to publish my app again. I renewed the certificates, updated my provisioning profile and signed a new app version to publish only to find out that the app crashes during the splash screen. I added new features to the app so my first thought was that there would be an issue there. To test that, I built the latest stable version of the app and signed it with the new profivisioning profile. The result was exactly the same crash as the new build. My assumption is that the crash is caused by bad signing (?) but I am not sure because I'm lacking experience on that front. I do have a crash report from testflight and logs from the device where the app crashed. Testflight crash: TestFlight crashlog Device error logs: Device error logs Hope someone can help my out because I'm at a dead end :(
