I've used them both in custom post type mode with no problems. I changed to post formats and at first everything seemed to work all right. I could post new posts with format from the dashboard widget or post editor and even posts created from syndicated feeds were assigned post formats.
Then I noticed that icons were shown only on posts posted from the backend. First I just couldn't understand but after some digging in database I found the problem. Both plugins create their own post_format taxonomy in term_taxonomy table. So I got two post_formats in my db one for post published from the backend and one for posts from feeds.
Any ideas how to resolve this issue?
