Some of you may have received an email like this for the TP. I did and when I went to correct the information, it said it had already been edited and couldn't be edited further (I did nothing). I worried for a while that my application would be delayed. But, to my great surprise, I received my TP QR code hours later! Four days wait for me (Wednesday night to Sunday night, USA time).
So, if you get this message and you can't edit the info, most-likely someone on the other end already corrected it.
TLDR : Answer Summary
If you receive a message indicating that your TP application information has already been edited and you cannot make further changes, don't panic. It's likely that someone has already corrected the information on your behalf. Many users have reported similar experiences, where they received their TP QR code within a few days despite the message. Be aware of date formatting differences, especially between the USA and other countries, which may contribute to confusion.
