Hi,
I’ve just copied the meta tags to my theme.liquid and submitted my sitemap to Google successfully.
But Google Search Console says it “couldn’t fetch” the sitemap.xml.
Not sure if it takes time to crawl my page or I’ve done something incorrectly.
Here’s a report.
Thanks for your help from a first timer so a little more anxious. 
Hi,
Hope you have submitted the correct url
If the sitemap URL is correct, please note that this error is known to occur for sites hosted with any company
In most cases, it resolves itself within a couple of days or weeks. However you can submit the URL using the Inspection Tool to speed up the process.
Also submit below individually at sitemap
