I understand that in order for me to mention a Facebook page before submitting it for approval I must be posting as a page I admin, tagging a page I admin and using an app I admin - otherwise, the tags are not applied.
The problem with this is that test users are not app admins. I know I can use my personal account since I'm an admin of the app, but I want to avoid creating actual Facebook accounts/Pages to test this functionality. I would like to know how/if it is possible to test page mentions using a test users account.
This question is what made me realize that I was going about it in the wrong way, but still leaves me with the question I'm asking now. Thank you in advance!
UPDATE
I reached out to Facebook and It is not possible to use test users for page mentions. The only way to test this functionality is with your personal account (or real FB accounts that admin your app).

Hope this helps someone in the future!
