Changes made while doing shopify app dev don't reflect in cart transform function

I have to deploy the app every time I want to see a change reflected in a function I’m developing while running shopify app dev.

This has happened on and off or months now.

Hey Kalen, when running shopify app dev it will make available the new function only to development stores. Can you double check the store you are working on is in fact a development store?

Maybe it’s because it’s a weird plus semi-dev store:

But I’m almost certain it’s a dev store because won’t the cli throw an error if you try to app dev against a non-dev store?

Also it’s been a while since I was working on the discount function in this store but I recall it worked more reliably.

That seems to be the source of the issue here: app dev

Note: Development store preview of extension drafts is not supported for Plus sandbox stores. You must deploy your app.

Aaaaah - thanks for clarifying. This was driving me nuts. I wonder why sandbox stores don’t have better support for this. What’s the official recommendation on doing development for plus stores? Are you supposed to use a dev store instead of a plus sandbox?
