My code is not updating the main theme while the dev theme is displaying a delayed version

Topic summary

Theme changes do not reliably appear on the share preview link. Updates show in the author’s main browser, but not in other browsers or incognito sessions, indicating inconsistent propagation.

Environment/workflow: Editing theme code in VS Code via GitHub. Also tested making changes directly in the Shopify theme editor.

Attempts: Pushed updates through GitHub and edited directly in the theme editor; neither ensured immediate or consistent reflection on the preview link.

Observed behavior: Intermittent, delayed updates (“weirdly delayed updates from time to time”). The discrepancy suggests that the preview sometimes serves older versions even when the local view appears current.

Impact: Inability to validate current design via the shareable preview, complicating testing on other devices/browsers.

Status: No resolution or confirmed cause identified in the discussion. Key questions remain open regarding caching, deployment lag, or preview behavior, and no concrete action items or fixes were established.

Are you having issues with your theme editor?

My updated codes are not reflecting my design if I will use the sharepreview link. It is working fine in my browser but if I will use a different browser and incognito ones it is not showing. I am coding in vscode through github. I tried directly to the theme editor and it is still the same.

I am seeing weirdly delayed updates from time to time.
