1. The app is not user-friendly for beginners to indexing.
2. The video tutorials are not as helpful in the sense that it is taking an already done example to explain, not from the beginning.
3. The person in the video is hard to understand due to his accent. A user manual will help better.
4. After uploading the sitemap index, the app is not picking up the URLs under the sitemap. In Google Console, the sitemap index has several sitemaps inside and the URLs are under the secondary sitemaps.
5. There's no instant help or support provided.
I gave up after fumbling here and there. Heck, the button to the site maps is also quite hidden. Overall, this app needs extensive overhaul on the user-friendly section.
