This is the result of a misconception that if they changed the second letter to a number, then the new ID would be automatically accepted. But they would not listen to the criticism and implemented it their way.
Now all ARC checks have to be updated to accept the new ID format. There will be many places/websites overlooked until enough people hit the brick wall and complain.
I had to get new ID. I am now not using the old one on purpose. I want to force the companies to update their software. More and more people will be changed to new ID format and it will be a big nuisance for everyone.
