Yep, that really isn't a good feeling to have to use the ACTIVE key to login! While searching for a solution i came across only one post on steemit by @exyle from 2 months ago in which he writes that you get logged in at busy.org automatically when logged in with your POSTING key on steemconnect already, but that didn't work, at least not for me. I wrote and asked him about it, but have no answer yet. Maybe i mixed something up, check teh post here: https://steemit.com/dtube/@exyle/fct86la7#@moretea/re-exyle-fct86la7-20180303t140433737z
