Good morning Neuhauser,
I see it's your first post here, so welcome to the community! Thank you for these details, this helps. Could you please tell me where exactly in the new registration process you run into an issue?
Using your SAN and phone number, I was able to get to this point. Are you able to do the same?
I removed the parentheses and dash from the phone number, but left the dash in the SAN, and I was able to get to step 2. If you are seeing an error message, please share a screenshot of the error message.
Your cooperation, patience, and understanding are much appreciated.
