The following discussion from !21497 (merged) should be addressed:

  @cwiesner Should it be tested on production or canary? In production the field is there but there are incorrect results. I've found at least one user where the value is Yes but they are not a member of a paid group.

  @tyleramos and I just looked into this and found out that the issue here could be related to the change in !20664 (merged). Because it does not take a Free plan in consideration. It only checks if the plan is Ultimate, if not it always returns true. But if you're on a Free plan the members should probably not use a seat.
