Trouble With Multiple Schedules

I use this plugin to post Instagram images to our Insta landing page that then link to their respective pages on our website. This was working fine up until about a month and a half ago. I schedule 5-10 updates at a time… so I schedule an update to the Insta page, then I need to schedule another update to the scheduled update page, and repeat this process. If that makes send.

Original
Scheduled Update A
Use Scheduled Update A to create Scheduled Update B
Use Scheduled Update B to create Scheduled Update C
Use Scheduled Update C to create Scheduled Update D
Etc.

When scheduling, I’ve tried creating a New Draft from the Scheduled Update page and click Scheduled Update on the new draft. Didn’t work. I’ve also tried Cloning the Scheduled Update page, then Scheduling from the Cloned page. That also didn’t work.

What are your best recommendations for getting this plugin to work again for what I need? Or does anyone have alternate plugins they can recommend for this process?

Thank you in advance!
