I am having troubles playing Rainbow Six siege, no idea why because I was playing fine yesterday. Though it is unable to authenticate ownership of the product. I bought the product from steam if that helps. Are there any suggestions to be able authenticate ownership?

Hey XxCapt_GamaxX,

This issue usually occurs when you're logging into different Steam/Uplay accounts.

Please ensure you're logging into the correct combination of accounts that Rainbow Six Siege is linked with.

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??
