My website has two domains: one for desktop, which is abc.com (for example), and another for mobile, which is m.abc.com. After shifting the mobile site to a new design, the canonical tag on the mobile version was mistakenly set to m.abc.com by my tech team. When I noticed this after the weekend, I asked them to change the canonical tag on the mobile site to abc.com because I want the desktop URLs to be the preferred version. They made the change, but now the issue is that despite this, the m.abc.com pages are still ranking on desktop. Even after updating the canonical tag, the mobile pages are continuing to rank in desktop search results. How can I fix this, and what should I do next?
