Yes it works like a charm! Thank you.
v1.6.1 theme has been published here but without it's child team sidekick
By the way I tested using v184.108.40.206 BuddyBoss theme with v.1.6.0 child team: it seems to work but can't guarantee that problems won't accrue farther along the way.
So if one of you have access to v220.127.116.11 child theme, please share !
*Update* In fact normally child theme doesn't have to upgrade with the theme (that's why child themes exist in the first place, to allow upgrading theme and keep your child theme...).
So it's perfectly safe to use theme v.18.104.22.168 with older child theme.
