At the time of writing, it is currently Season 3 of OW2.
My shop still displays Season 2 items. For example: ‘Starter Pack: Season Two’, ‘Premium Battle Pass (Season 2)’.
This hasn’t bothered me much as I had no desire to buy anything from the store. However, with the introduction of the One Punch Man event, I wanted to buy a skin or two but obviously can’t, as my shop is still displaying stuff from Season 2.
This account has never had a migration from a console or otherwise had a data issue.
I do apologise if this bug has been reported before, however, I have not seen one which matches my issue.
Thanks.
