Build for iOS - Unknown Error

I’m trying to release an iOS version of our app but after I completed configuration an Unknown error came up.
Can you please tell me if I did something incorrectly?

many thanks

When you get those errors you should have received an error log emailed to your email address. They are usually pretty long so I find it easier to just search for the word “error”, and that will usually reveal where your problem occured.

Hello John, thanks for the reply!

I tried to complete the iOS configuration and build several times. I always get some kind of error but none of these times I received an error log. I’ll keep on waiting for a reply from the support.

Many thanks
