I removed the Facebook App and tried to clean up my information, before rethinking it back to Facebook. I wanted to remove all traces of Shopify in Facebook before properly linking it.
In Business Manager
Under System User: I can't remove
Shopify System User for Resource Management
Under Pages it shows the following 3 times, If I try to remove it says there is a technical difficulty. If i relink it ends up adding a fourth user with the same name.
