Hello Tony_Danza0
If you are referring to the shapeshifters evolutions from last season, finesse+ and quick step+, if you ever did have them, they should be in rewards and cosmetics, and display "expires in 6 days" as of right now.
If you mean that you didn't claim them from the season pass, then unfortunately there's probably no solution for this.
I was under the impression that unclaimed season pass rewards would be automatically claimed at the start of a new season, but according to the reports here, I may have been mistaken. Because I have never tested it myself, fearing it too risky, I have no firsthand knowledge of whether this is true or not. I will just tell you what I do. Since the premium pass has been out, because my money is tight, I have been waiting until the last week to claim rewards. I buy the pass, then head to the companion app and go one by one, claiming and picking rewards. I understand that some picks can be difficult, please always be sure to claim each level manually. Also, there's no risk to claiming season pass evolutions at all. They'll expire on the same date regardless, and it's usually multiple weeks after the pass expires, so definitely be sure to claim those the next time.
Thanks for your question, I'm always here to help, but unfortunately I don't have solutions for expired or missing content.
All the best to you!
