[Bug]: Shopify CLI (v3.70.0) Bug: Settings Not Updating Without Multiple Saves

• Reproduced the issue in the latest CLI version.

In which of these areas are you experiencing a problem?

Theme

Expected behavior

It should save and synced every time.

Actual behavior

We are encountering an issue where settings only appear after saving the file multiple times, which significantly disrupts our workflow. Each time we make changes, we have to repeatedly save the file to reflect the updates, which is both time-consuming and frustrating.

This issue persists across multiple development environments, and we are confident that it stems from the Shopify CLI. We are currently using the latest version (3.70.0) of the CLI, but the problem remains unresolved.

We would appreciate a resolution or guidance on addressing this issue to streamline our development process.

Repro steps: See attached screencast:

See below screenshot, all times files are saved but not synced with editor:

Here it is our environment for development:

[environments.dev]
store = "store-name"
password = "shptka_token"
theme-editor-sync = true

Verbose output

shopify theme dev -e dev

Files are not being saved and synced with editor on single save. But on terminal its showing files are synced correctly.

I believe this should have been fixed by #5042

I believe this should have been fixed by #5042

That fix was released in 3.72.0 today. Can you try it @shopify-development-code ?

[shopify-development-code]

@frandiox thanks for your response. We will check it and let you know.

[shopify-development-code]

The issue still persists.

@frandiox @catlee This is still a problem.
Only in my case the problem with hot-reloading a CSS file. It needs to be saved twice for the CSS to take effect.
I'm happy to open a new issue if it's not the same as this one.
I tested it on a fresh Dawn theme with CLI 3.73.2.

To reproduce:

• Run shopify theme dev
• Add anything to a CSS file
• Save once

Result:

• Console shows [HotReload] Event data: {type: 'css', key: 'assets/base.css'}
• New CSS not applied

@kyrylo-soulandwolf This seems unrelated to the main issue. Can you check in the network tab if it is downloading the new file? When I try adding something like * { background-color: red !important; }, it updates the CSS in the browser 🤔 -- Please open an issue with your network tab findings if it doesn't work.
