Error: "Facebook fundraising is currently only available in certain countries. Your location does not support donations at this time."

I have an elderly family member who wants to donate to causes through their facebook, but they get the error message: "Facebook fundraising is currently only available in certain countries. Your location does not support donations at this time." They are in the US.

Cache's have been deleted, location tracking is on for god's sake, looking in FB settings I can clearly see their location marked correctly, but still getting error message. We tried creating a new FB account as a different person on their computer and that new account (same computer, same browser) had no problem donating.

any thoughts? thanks
