Hi there!
Please try relaunching the game. If this doesn't resolve the issue, verifying your game cache may help!
1. Restart your computer and launch Steam
2. From the Library section, right-click on the game and select Properties from the menu.
3. Select the Local files tab and click the Verify integrity of game files... button.
4. Steam will verify the game's files - this process may take several minutes.
I have done all the steps and it still says, "requires season pass" when I try to claim rewards. I did buy the season pass in the beyond light bundle but it says I own beyond light so would that have anything to do with this problem?
