Did you sort this out? I am having the same issue and have been going in circles for weeks. Let me know what fixed it please!! 
Topic summary
Google Search Console (GSC) is not reading a Shopify store’s sitemap after ownership was verified via the URL prefix method. Submitting the standard sitemap URL (/sitemap.xml) returns “Sitemap could not be read.”
Actions and checks:
- Submitted https://doodad.co.in/sitemap.xml as advised; GSC still shows the same error.
- Reviewed sitemap “checkpoints” per community guidance; no errors found in the sitemap file.
- Multiple submission attempts made without success.
Artifacts:
- Screenshots show GSC’s “Sitemap could not be read” status and a separate sitemap validation indicating no errors.
Community input:
- One reply suggested the correct sitemap URL (already tried).
- Another member requested an update, reporting the same issue and seeking the fix.
Status and open questions:
- No resolution reported; issue remains ongoing.
- Cause of the GSC error is unclear despite a seemingly valid sitemap.
- Request for alternate solutions or next steps (beyond re-submitting /sitemap.xml) remains unanswered.
