I've been trying to fix that issue for a while and couldn't find a work around.
So this is what we have in the Shopify settings
And this is what is showing up:
You can notice than even the title is not showing up properly.
Sitemap have been updated last week and I forced a recrawl on webmaster tool last week too.
Still a weird glitch. Does anybody knows how to fix that ?
Ava here from Shopify :)
I'm afraid this would be controlled by Google. Once the meta description in Online Store Preferences has changed and saved, it will take Google some time to recrawl your site to take the changes into account. After you've already manually updated your sitemap and resubmitted the results, it will be up to Google to push these updates through. So there is nothing more to be done on your end, just to wait for Google.
I wish there were more we could do here to push it through! I'm sure Google will update these changes soon.
Let me know when you have an update!
