Blogger 301 Redirect Not Working on Mobile Devices

Hello.

I migrated my old free Blogger-hosted site to a self-hosted WordPress domain. I had some posts that had relatively decent SEO rankings so I used the Blogger 301 Redirect plugin to redirect users from my old Blogger pages to the corresponding WP pages.

It worked perfectly. I was able to redirect posts from Blogger to WP. I was also able to change the permalink structure (I removed the months, years, and dates), and I was also able to eventually edit the permalinks of the posts that were transferred from Blogger to WordPress (I mostly just shortened the new permalinks), and everything is still getting redirected from Blogger to WordPress properly.

This is when I’m using the desktop version.

Today, however, I accidentally found out that pages are not getting redirected at all when I’m using a mobile device. I tested several pages and I always get the same result.

Below are some sample URLs:

Old Blogger URLs

https://philippinehalohalo.blogspot.com/2012/08/tagalog-adverbs.html

New WP URLs

https://philippinehalohalo.com/tagalog-linking-verbs/
https://philippinehalohalo.com/what-is-the-difference-between-ng-and-nang-in-tagalog/
https://philippinehalohalo.com/tagalog-adverbs/

They redirect just fine in desktop mode (works for Chrome, Firefox, Bing, and Edge) but it’s stuck at the old Blogger page on mobile.

P.S.

I’m not sure if my internet connection is just slow, but the redirection looks relatively slow to me. I’m guessing it’s because the pages had to go through a transition or maybe because I changed the permalinks, but is there a way to speed it up a little?

P.P.S.

I’m using WordPress 5.3 and the Amamorize Version: 1.0.7 theme.

Thank you.
