I have uploaded my app to App Store Connect TestFlight. Then I have downloaded it in TestFlight on my iPad. But the app always crashes a few seconds after opening. It seems to be always the same issue. I have a few crash reports in App Store Connect-->App name-->TestFlight-->Feedback-->Crashs. I have opened a crash report in Xcode but I don´t find the error that causes the crash. How can I find the error in Xcode? Is it possible to find the class and line in the class where the crash happened? In addition, how can I export a crash report from Xcode? The crash doesn´t happen in debug mode on my iPad, it only happens when I install and open my app after downloading it from TestFlight on my iPad.

I created my account many years ago. Now I have a D-U-N-S number and I want to enter it. Where can I enter it in my account?

Where can I find the in-app purchases transaction details in my Apple developer account? I need to know this because I want to find out if a player can get a refund if something went wrong with the in-app purchase. In addition, my application is not published in the App Store. I use TestFlight to test the in-app purchases. Are the test in-app purchases recorded somewhere in my Apple developer account?

What should I do when my Development or App Store certificates in my developer account under Certificates, Identifiers & Profiles are almost expired or when the certificates are already expired? What should I do so that I can still use the certificates? What happens when the certificates expire and when I already have an application in the App Store?

My application always crashes at the same position when I open it on my iPad Air. It doesn't crash in debug mode which makes it very difficult for me to find the issue. My crash report from TestFlight: Exception Subtype: KERN_INVALID_ADDRESS at 0x000000016d5f26f0 Exception Codes: 0x0000000000000001, 0x000000016d5f26f0 VM Region Info: 0x16d5f26f0 is not in any region.

I use Moho Studio on macOS to create an icon and a launch screen for my iOS application. But when I right click on the exported png file then I can see that the color profile is missing. I have tried to add this png file to Assets-->AppIcon image set in Xcode and I got no error message because the color profile is missing. My png file looks like this: Is it possible to use png files even if they don't have the color profile sRGB IEC61966-2.1? Is it possible that the images won't display correctly on an iOS device because the color profile is missing? I cannot add the color profile in Moho Studio. I would need another program if it is necessary to add the color profile to the png files. Which program should I use if I need to add the color profile to my Moho Studio png files?

In my iOS game, the player must create an Azure PlayFab account and then the player can login with his email address and password in my game. Currently, players cannot delete their account in my game. Is it necessary that there is an option in my game where the player can request to delete his Azure PlayFab account? In addition, is it necessary that the player can request the deletion of his Azure PlayFab account on my game's website? I don't know if my game would get rejected in the App review if players cannot delete their Azure PlayFab account.

My Apple developer certificates(4 certificates) expire soon. I'm developing an application for iOS but the application is not yet released in the App Store, only Testflight releases for private testing. Is it necessary to create 4 new certificates or can I edit the current certificates so that they don't expire soon?

I need a privacy policy for my game. I want to upload my game in the Apple App Store and Google Play Store. In my game the user needs to create an account(Microsoft PlayFab) and I collect the user's email address and password. In addition, I use Microsoft Visual Studio App Center for Crash reports. The crash reports are automatically send if the game crashes. Do you know a good generator or samples that I can use to write my privacy policy so that my game doesn't get rejected?
