Im try to implement Login with Facebook feature for my Unity game. It's weird that when have the facebook app on my phone, it show the error message :
Invalid key hash. The key hash MhmZ*************** does not match any stored key hashes
it's weird cause when I use the openssl to create SHA key, it's different. the result is Bmce+***************
However when I delete the facebook app and try to login again, (it will login by browser) and it works.
I tried to copy the key hash in the msg MhmZ****** and pasted on the developers page but it still not working.
I hope when user already has the facebook app, they can still login to my game.
If anybody knows why this happend please let me know. Thank you very much
