Before the advent of the much more powerful and flexible Advanced Registration System as a way of adding additional questions/fields to Registration and Opportunity signup - HandsOn Connect users could only create custom questions for Registration using the Control Panel's "Volunteer Registration Questions" interface.  For the handful of early HOC users who are still using this functionality instead of the ARS, we've updated the interface to make it work without issue in SF Lightning.

It was discovered that a volunteer could not remove themselves from the waitlist of an occurrence that has been cancelled.  (They wanted to do so because they decided to sign up for another occurrence taking place at the same time).

To prevent this conflict, when an occurrence is cancelled, all connections (not just confirmed ones), will be put in attendance status = cancelled.  As such, pending and waitlisted connections will not be evaluated as conflicts to signing up for another occurrence taking place at the same time.
