In 2023, the third largest election in German, the social elections (in German Sozialwahlen), offered an online channel for the first time. Of particular interest is the fact that the system provides a form of cast-as-intended verifiability, allowing the voter to verify that their vote was cast as intended and not manipulated by the device they used to cast their vote. This paper describes a first analysis of the overall voter experience with a special focus on this verifiability functionality. We utilize a cognitive walkthrough method, with three people having different levels of expertise regarding online voting, including a layman, a security expert, and a voting expert. Our findings reveal a number of issues with the system in terms of communication and presented information, and highlight areas in need of improvement to enhance user experience in particular with respect to the verifiability functionality.
