Schedule study plan

I have been trying to add a schedule to a study plan and it won’t work. The message tells me to create a new plan to add a schedule but that doesn’t work either. I have done this in the past but I’m not sure why it’s not working now. Any help or suggestions would be greatly appreciated!

I use both an iPhone and an iPad.

I am trying to find the featured study plans on the Home Screen on the Gospel Library app. I only see the button to create a custom plan. How do I get the featured plans to populate in my study plans?
