Hey @Ria82! If you duplicate an automation, it will not also duplicate the sequences within it. That is, the duplicate automation will still be connected to the same sequences as the original.
Since we prevent subscribers from receiving the same emails from the same sequences more than once, this can prevent your subscribers from receiving your content as expected.
I'd suggest making sure that when duplicating an automation, you are also duplicating the sequences (which you can do from their settings pages) and switching out the sequences in the duplicate automation to ensure it's connected to the new ones and not the originals.
I hope that helps! Let me know if there is anything I can clarify further 😊
