Hi, I am the maintainer of an adhoc app we use in-house, and every year, we need to update the certificate and re-compile the app. This year, I encounter a new problem. It seems I can't add my account to Xcode. (changed computer) Xcode is at the last version available from the App Store (version 11.6). I updated MacOS to Big Sur. The developer account itself is renewed. What happens, is that from Xcode, I have an unknown error when I try to add the account. (I checked the ID and password multiple times, and I can login to itunesconnect with it) The account has the roles "Admin" and "owner". The developer options are checked on the profile. Without that, I can't check the application on my iPhone. I feel that there is something obvious I didn't see yet, maybe I had too long of a day... Any help on that matter would be greatly appreciated. Regards, Cedric Simon
