segmenting by session source in mixpanel DataNinja 10/02/26 (Fri) 13:54:26 84e74 No.2266

tried using the properties view but it keeps grouping everything into one giant bucket. i think my event property mapping is broken since it's not respecting the individual session parameters at all.

Check if your event properties are actually being sent with every single event, because Mixpanel won't split them if they only attach to the first one in a session.

i don't think that's actually why you're seeing one giant bucket though because mixpanel usually carries those properties forward through the session automatically once they are set. if the mapping was truly broken you'd probably see a bunch of null values or empty strings instead of everything just merging together into one group. have you checked if there's some kind of global filter overriding your properties in the report settings?
