As of oct 18th our facebook sales started declining hitting 0 purchases 4 days later and staying there ever since. When a player clicks a product to purchase the facebook purchase ui either doesn't pop up or immediately closes itself and returns an error that the user canceled the order. With further error logging it seems to first spit out "couldn't complete payment you aren't currently eligible to make payments using meta pay.", then gives us the result code of 1383250. we've tested specifically on windows 10 with chrome and firefox, but as I said our web revenue has dropped to 0 across the board so it must be affecting all desktop environments. We are using the facebook unity sdk version 16.0.2.
