πͺ When multiple contacts merge, we were losing some transactional data associated to the deleted contacts.
We are now merging Purchase History, Bookings and Stays as well as PoPs and Contact meta information (asynchronously) into the remaining contact while maintaining timestamps. We also return a new flag in the response "merge_in_process: true" to signify that merge is processing and some of the response data is not 100% accurate until that is completed.
