[Update September 23rd 11:00am]
We have identified the issue with Switch players not being able to purchase Days of Summer Lanterns. We expect all regions to have access to being able to purchase them on Switch by October 1st. We will provide updates if this changes. Thank you for your patience.
We are currently aware that Switch Players are currently unable to purchase the lantern in the shop. We will update this post once we have additional information. We appreciate your patience during this time.
