Welcome to Shopify Community. My name is Olivia and I work here.
Thank you for sharing your question with our network. I looked into this further for you, and it appears that Facebook sometimes implements these restrictions on certain websites they believe are not compliant with their standards and guidelines.
For further context, check out this similar question in the Facebook Community with a potential solution listed by the Facebook Help Team. If that does not work, I encourage you to connect with Facebook Support directly for further guidance and personalized assistance.
I also invite you to share your website URL with us here for feedback from our network and other business owners that may have faced a similar issue.
We look forward to your reply,
