I installed Shadow Legends (SL) on my iPhone... I played that a lot... Got connected with FB and I created a Plarium ID (...and connected that with app).

Then I unfortunatelly found myself in a situation installing the game to my iMac !

Since then... on my iPhone this game got started from the very begining.... with some new credentials USER ID xxxx | xxxx and since then, I am STILL not able to login on iPhone to my own and very first Plarium ID... and to retrieve my achievements / progression within the game on iPhone as when I try to login to my Plarium ID... it just simply replies, I am already logged on somwhere else... although I am not!

Because I logged out myslef on iMac already !!

Well... Just log to your FB through the game and everything is back in normal.

Thanks and have fun ! :D
