Google Search Console "International Targeting" is reporting errors that are not present on my site

[Starcom_Search]

We are currently handling search for a global brand www.example.com/ which has presence in many countries worldwide. To help Google understand that there is an alternate version of the website available in another language, we have used hreflang tags.

These hreflang tags are implemented only via the XML sitemap across all geo-locations.

Under the “Search Analytics -> International Targeting” section, in Google Search Console, for the Malaysian website (www.example.com/my/), there are a number of “no-return tags (sitemaps)” errors arising.

For example, for India as a geo-location, there is one ‘en-IN’ – no return tags (sitemaps) errors listed. The error is listed below:

Originating URL - www.example.com/my/xyz/

Alternate URL - www.example.com/in/xyz/

When the XML sitemap for the URL – www.example.com/in/ was checked for the hreflang tags, it was noticed that the implementation of hreflang tags for the URL – www.example.com/in/xyz/ was perfectly fine and it was providing a return tag to the URL – www.example.com/my/xyz/. After the code level verification, it was identified that the implementation of hreflang tags was perfectly fine via the XML sitemap.

Even though at the code level it was verified that the implementation is fine, the error still persists in Google Search Console.

Kindly suggest a solution to this situation, and also advise the effects of these errors on search engine performance
