We understand that there are some privacy concerns around collecting client_ID, however, the repercussions of not having this is that we won't be able to tie any of the snippet-related Retention efforts to aDAU, which is essential for the existing user aDAU and LCM teams. Michele Warther will be syncing up with Marshall/Michael (legal) to get this conversation going to provide a green light - in the meantime we wanted to be sure to file a bug so you could track the effort. Thanks, Lisa
