We sent out an email to all partners and customers with historical accounts (claimedIDs) pointing to the Issuing CA4 for EU signature certificates (QES and AES). The siganture applicaiton must be adapted to the new Issuing CA 4.1. The details were sent out in June. The work must be finished until Dec. 31st, 2022 since the old issuing CA will be deactivated afterwards and signatures with this issuing CA will be no longer possible. Please plan these adapations (in principle it is the renaming of the claimedID). Thank you.
