Hi Chriso,
I am trying to do this exact same thing but I am not seeing ‘labels’ or anything vagueley similar to ‘association’ in my options, other than ‘Number of Associations’.
Therefore I am unable to create these filters. Are you aware of whether ot not there has been a change of name for this filter option and if so, please do provide some more specific guidance.
I have searched under both Contact and Deal properties in the list filters.
