The original problem was on a windows 10 machine, I get the same on Linux - and now I have just tried it on my S21 Android phone and I got the same result - thats on the mobile network not wifi so completely different connection. The trifecta - Windows, Linux & Android, no VPN, all the same result.
I tried to lodge a question to Paypal, all I get is the chatbot giving me the same references to look at, to understand why it's something I am doing wrong...as if, I am doing the same prcess I have done since finding MC at version 22. Then it eventually it askes - "will I Send a notification to customer service" ... Ah Yes! Then Paypal says it will "get back to me" - not holding my breath.
