QuoVadis has made a change to the certificate chain that affects some Qualified digital certificates issued by QuoVadis EU Issuing Certification Authority G4.
Customer end-entity certificates themselves are not affected by the change, but for some users, starting on October 15, 2019 it may be necessary to replace the Issuing CA in order to maintain automatic trust chaining.
The change does not pose any security risk to customer systems and
is intended to maintain compliance with browser requirements.

If your computer has this version of the G4 certificate, it must
be replaced or your end-entity certificate may not work properly after
October 15, 2019 21:00 GMT.
