trying to implement the new Facebook local currencies, and I keep getting error code 1353028 if I set a user as a payment tester. if I remove the user from the payment user the payment dialog will open correctly.
the app is in sandbox mode, and the mentioned user has a "tester" role. I also tried disabling sandbox and removing the user from being a tester, just leave him as a payment tester, but still not working.
what else remains to try? anyone else experienced this and found a solution?
and why on earth would Facebook prevent app admin/developers from being also payment testers??
