Hello. I linked my account to my steam account, and there was Rainbow Six Siege at my steam account but when i checked ubisoft connect there wasn't my game and it asked me if is this my account and i said yes but it didn't work aswell.So i cannot play it anymore.I appreciate it if you can help me.
Hey yimur07, thanks for getting in touch and welcome to forums!
As it stands, when you purchase Ubisoft games through Steam and you launch them for the first time, you will be asked to link it to Ubisoft account, therefore if you activated it on any other Ubisoft account, that will be the reason why you're unable to see it in your library.
If you need assistance recovering account where it is linked to or if you wish to transfer your game to another account, we're happy to look into it, however I will need to ask you to reach out to us via one of the following channels:
1. Support website
2. Facebook
3. Twitter
Hope this helps. Should you have any further questions, let us know!
