Why is my checkout suddenly disabled on my IOS Shopify app?

[Zenmindco]

I have had the same plan for almost two years but for some reason when I went to share a product like today via Shopify app for IOS, it notified me my checkout is disabled and I need to select a plan. I went through and selected the same plan that I already have that is already connected to my credit card and it is still giving me this message when I go to share the product link. 
What do I do? Is it a false message? A glitch? This has never happened before.
