As an Admin with full privileges, I am not able to view the member's only pages that I create myself because I am not a paid member via the definition given by Wild Apricot. If I build a member's only page and attempt to view it, it returns a 403 error.

Please add a category to your backend that automatically allows the person who has authorization to build the page to actually view the page as they build it.

Setting up special non-paid membership categories to add admins to so they can view the pages they build is a terrible workaround.
