OpFindFriend() returns friend is offline although friend is online.
My logic is that Player A and other player are in a room. And then, player A create a room and other players in room find player A's info with OpFindFriends() and join player A's room. It works perfectly fine for months. But, suddenly other players frequently get updated as player A is offline although player is online and successfully created a room. To make sure, I waited OnFriendListUpdate() for five times before deciding the player A is actually offline. Every time the player A information is returned as offline.
How can I test Player A is actually went offline? Or, is this the bug from PUN?
