I create the CSR through the generator in the wizard and then make the proper distribution certificate from the Apple Developer account - but I’m getting this message “Oops! The certificate type (null) is not valid for distribution.” when I upload the Distribution certificate back to the thunkable publishing wizard.  
Am I missing something?

Thank you in advance
