Sitemap / Server side bug not fixed - waiting 2 weeks now - lost Google indexation

We have a critical sitemap issue that’s been escalated to Shopify’s development team for 13 days with no resolution or timeline.

Issue: Multi-market sitemap generating 4 language versions instead of 2, and individual sitemap files return HTTP errors when accessed. This has caused our Google Search Console to show zero good pages. And search results are now poor and all over the place.

Support ticket # 64129866 escalated to dev team Feb 18, provided technical root cause Feb 23, silence (except thanks for your patience) despite multiple follow-ups.

Business impact: Traffic has dropped to near-zero due to this platform bug.

Can a community manager please help escalate this internally? We cannot get any response / resolution through the normal support ticket.
