I’m working on a workaround needed to resolve issues with the Calendly App integration, and one possibility involves branching to a new question if the user doesn’t select a date/booking in the Calendly App question.
The issue is, how to I set up the logic surrounding an unanswered Calendly question? In the logic dropdown I don’t have ‘is unanswered’. My initial plan was to trial-and-error what’s there until something worked.

In an attempt to ‘set is equal to’ an empty space (in essence, if #10 is left blank with no answer) results in an error message saying it can’t be left blank, and to try flipping the logic to ‘is not equal to’ instead.
Attempting to do that, I’m unable to successfully save the logic. Clicking ‘save’ doesn’t close the box, but when I click ‘cancel’ or the ‘x’ and return to the logic view, the logic seems to have been applied. That is, until I click ‘Publish’ and receive the following error:

Refreshing the page eliminates the apparently saved logic, and I’m back where I started.
I’ve attempted to apply any logical expression to the Calendly question, and this same process repeats. Does the Calendly App integration not work with logic? Or is this just a bug that needs squashing?
Any help is much appreciated.
