For a customer, we retrieve collections via the Storefront GraphQL API. First time visitors receive the latest data. While if you have visited the website before, it shows old collection information. When you use incognito, this changes nothing and you still get served the same data. Based upon this, it feels like there is a caching layer causing the old information to be shown.
Does anyone know if something like this is in place and if you can reset/ignore it?
This problem causes issues as customers are served old collection information, incorrectly informing them of products that can be bought.
