Finally got it to build properly and uploaded to the AppStore. The trick seemed to be to use a different identifier than what I have used before even though it was identical to the original one. I also (as I figured out before) I needed quit and restart VS for the changes to take effect. Once of the proper Provisioning Profile was displayed.
Xamarin IOS Unable to Set Provisioning
This is for an app I've published for several years but apparently some changes in the way credentials and provisioning works are giving me headaches? This is for a release AppStore build as the usual setting work fine for debug. The specific provisioning profile shows up in the list when Manage Accounts is run but can't be selected for Manual Provisioning. Either I see No Matching Profiles or the Wild Card provision which is for debug. If I include the correct Profile in the project file it gets prefixed Unknown.
I've gone through the steps to verify that the chain of documents to make this work are correct. I've read through numerous reports of people having similar problems often without an answer or solution. Apple's method seems overly complex and abstruse when compared to Microsoft and Google certificate processes.
This takes place on VS 2019 on Windows (vers 16.10.4) and have even tried it on VS Mac with the same results. Is there still some VS bugs that need to be fixed because it has never been this difficult before?
