After researching on many forums, I found that the ‘Page is not indexed: Redirect error’ issue is because the new blogger crawls using ‘Googlebot Smartphone’ as the default crawl, so every time a web link is opened using a phone or desktop, the URL detected by Google's crawl engine is always the "?m=1" version.

To resolve the issue of Googlebot indexing the mobile version with "?m=1" and ensure that it crawls and indexes the correct desktop version of your pages.

I don’t know if this is a permanent solution or not but working right now.

As per Google, to create a Redirect for a URL to help people find your blog on search engines

1.     Sign in to Blogger.

2.     In the top left, choose a blog.

3.     From the menu on the left, click Settings.

4.     Under "Errors and redirects," click Custom redirects. Add.

5.     Add the deleted URL and the URL you want to redirect it to. If the original article was deleted, turn on Permanent.

6.     Click OK. Save.
