Error fetching session token on POS Product Details screen despite extension being disabled

Hello,

We are currently encountering an unusual issue regarding our POS UI Extension (scoped to the Product Details screen).

The Issue:
Recently, a couple of merchants have reported seeing an error message overlaid on the Product Details screen in Shopify POS. The error reads:

“Session token fetch failed or Wishlist Plus. Check {name} permissions”

The Context:
What makes this behaviour unexpected is that these merchants confirm they have the extension disabled in their POS settings.

Our Question:
If the extension is explicitly disabled by the merchant, why is the app context or session token fetch logic still being triggered? We were operating under the assumption that a disabled extension would not attempt to load or request a session token.

I have attached screenshots of the error below for reference.

Any insights would be appreciated
