The same problem here. Yesterday I lost over 1000 Instagram followers because the same post was being shared every 3 minutes, all night. The following morning I had to spend over an hour to delete all the duplicate posts.
I am not sure if the plugin author is interested in replying to any of the problems, never mind fixing them.
This used to be a really good plugin but I cannot rely on it any more. I am currently looking for alternatives.
