We do not support recurring posts, nor do we support evergreen or recycle content, at this time as we would like our users to create fresh content for their viewers to maximize their reach.
We also tend to be extra careful on the recurring posts subject as social media platforms are putting restrictions on recurring content, which could penalize your posts and our solution.
Currently, here are a few workarounds:
Create post templates from the Library: you can then create posts from these templates, but you will have to choose the date yourself when creating the post and make slight changes to the content
Duplicate posts: once a post has been created, you can always duplicate it as many times as you want and make minor edits
Create recurring custom post ideas in the Post Ideas Calendar View
If this a feature that you would like to see, please feel free to request it as a feature.
