I integrated Facebook SDK with unity to allow logging via Facebook it worked well in unity editor check here https://i.stack.imgur.com/f14th.png
void Start()
{
FB.Init(FBINIDONE);
}
void FBINIDONE()
{
string[] perms = { "public_profile", "email", "user_friends" };
FB.LogInWithReadPermissions(perms,LognDone);
}
but after building the game - the login did not work
1-locally -> did not work
2-online host -> did not work
3-Facebook canvas -> did not work
I googled too much , any other help ?
Not sure if this will help, but alot of the tutorials or step by step guides I found were outdated and would have errors like this if you tried them. I think this updated one might help if you have not already tried it
