Has a problem with new certificaion chains (like from Digicert) for monthes, simply ignores them.
Doesn't update the AATL for monthes, is erratic on handling it.
Doesn't take EIDAS solutions into account.
Has no direct interface to the e-signing process eg. of Austrian "Handysignatur" or "ID-Austria" signing, which is rolled out to millions of citizens.
Relys on funny "stick figures" instead of EIDAS.
Adobe should think outside the box, when major parts of the world set standards like the European Union.
