We've published a package with two artifacts in it (android and os) to Bintray: https://dl.bintray.com/gojuno/maven/com/gojuno/commander/
Then we've enabled sync with jcenter for this package, but only one of the artifacts is in sync (android is synched while os is not):
https://jcenter.bintray.com/com/gojuno/commander/
I contacted Bintray through Inbox on bintray.com, Contact Us on bintray.com, Email and Twitter and haven't received reply anywhere, this issue is blocking for the project.
I saw similar issue was resolved through StackOverflow Bintray and JCenter not in Sync, so this is my hope.
