I am just now trying to use automatic group placement within event registration. I have set up everything as documented, and have had another Rock admin screen share so that we could compare her setup to mine (hers works). I have been unable to get this to work. The only difference is that the other church (as well as the ones that have responded on chat) are in version 8.7 or lower. I am in 8.8 and have not yet had anyone verify that group placement does work in 8.8. I am thinking this may be a bug but unable to have anyone confirm.
