Hi,
I am also using Certum and Simply Sign...
I am doing the above with my Certum EV in the cloud certificate… “Issued to” is “Friedrich Linder”, so EVCS://Friedrich Linder. You have to find out what your “Issued to” is.
In SB2025 you’ll be able to use the thumbprint value here, but in 2019.7 you have to use EVCS.
