I saw what you said about having logged into different accounts... That's not the case with me... For example, I was able to play "Agos" for a couple hours one night, and the next day the "Ubisoft Connect" app failed me, with that above message... I tried MANY things, but can't get it to allow me to play ANY of my Steam-bought Ubisoft games!!
So, how do I fix THAT??
