7. Since I got my new Belgian eID card I'm no longer able to sign with eID
When I use my new eID card, eSignatures keeps prompting me to connect a card reader and insert my card, even though I've done so.
Cause
This issue occurs when you try to sign using the newest version of the Belgian eID card - v1.8, issued as of 2021/01/01 - while Connective Browser Package 2.0.6 is still installed on your system.
eID v1.8 cards are only compatible with Connective Browser Package 2.0.8.
Solution
Uninstall the current version of the Browser Package.
Restart the signing process using your new eID card. You are now prompted to install the new version of the Connective Browser Package.
How to do so is explained here: Windows / macOS.
Note that the installation instructions differ depending on the Internet browser you're using.
