Problem in Pro version: is not work

Hello
I installed the regular version of this plugin and it worked correctly
After two days I decided to buy the Pro version and I installed it and activated it and made it settings.
But this version does not work and does not send anything to my Instagram.
The only thing that happens is that every time on my Instagram I perform the identity process, and I confirm it, but there are still no posts on the Instagram.

I tested the regular version again and I saw that it works properly.
What is the problem?
