You may have applied too many times in the last 30 days. If you apply too often the system will just say no. I would wait 30 days before applying again. But this will give you time to review the data that needs to match and correct any errors in your credit report.
I can understand the challenges you’re facing. Here are several links to support articles that address a few of the challenges,

Manage your Apple ID
Because your Apple ID is used across all your devices and services, it's important to keep your account information up to date. Simply sign in to appleid.apple.com at any time to manage your account:
Confirm your shipping address is correct and matches the correct address on all your other documents.
• Lastly your application for Apple Card MasterCard must match all the above information.
A common error is expired Drivers License, and using an incorrect address or address that can’t be verified. Why can’t my address be verified? Check with the post office and see what the official address is for where you live. Then make sure your DL, credit report and you application and Apple ID have exactly the same address.
Why can’t Apple and GS help? My suspicion is privacy requirements and limits of the two companies policies. They share some information, but not all.
Why is positive ID required?
The Patriot Act requires that lenders, banks etc obtain a confirmed ID.
“To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. What this means for you: When you open an account, we will ask for your name, address, date of birth, and other information that will allow us to identify you. We may also ask to see your driver's license or other identifying documents.”
