Hello 

The problem appeared after RC1, when Custom Privacy Groups were added. From that time and until RC2 all newly created Group based profiles (Channels, Groups and Events) received pending status by default. We'll update such profiles on the next update but if somebody wants to do it right now then you may execute the following query in your UNA database:

UPDATE `sys_profiles` SET `status` = 'active' WHERE `type` IN ('bx_groups', 'bx_events', 'bx_channels') AND `status` = 'pending';

Best Regards
