This app and team have been improving non-stop and has so much potential. The only thing honestly stopping me from using this thing at 200% is the fact that I can't create posts without images (unless I still haven't figured it out.)
It seems like you need an image attached to the post content in order for it to even be drafted and scheduled. I know this is probably not how the tool was intended, but it's honestly just a quick toggle for image--less post option.
Considering that some text-only posts on linkedin and twitter go viral, it should be a no brainer to let users have this option.
I have added my suggestion to the ideas board, but please, for such a simple and necessary option could be added within the next sprint cycle!
