We warned Shopify many times that this would happen, they said it’s a non breaking change. We pushed back, but they didn’t want to listen.
Btw, it’s related to this announcement: Introducing the New Collections API (2026-07) — Developer Preview - #99 by Soufiane_Ghzal
@Tronquin just so you know, you’re not alone, this has been a pain in my bottom for the last 4 few weeks. The attitude of Shopify regarding this update is not understandable.
We’ve been stuck between a very short notice to upgrade - other stuff to do - if we upgrade we would potentially break other apps - if we don’t upgrade other apps will break ours - and Shopify claiming it’s non-breaking.
