Case update message from authorize.net on 2022-02-21:> The support team
is working on this issue. It seems to be happening to other merchants as
well. We do not have an eta on when this will be fixed.
I am having the exact same problem. Auth.net claims there is no issue. I
guess I need to file a support case? There's several other threads on
here detailing the same issue but no resolution.
