Anyone who’s having trouble getting their site indexed, I’d suggest using the rank math instant indexing plugin. For Google you have to take a few extra steps, which sounds daunting, but it’s actually pretty easy if you use this post from Rank Math to walk you through it. Hope this helps! I set it up day 1 and my site has 375 pages indexed vs 11 not indexed. https://rankmath.com/blog/google-indexing-api/?utm_source=Instant+Indexing+Plugin&utm_medium=Setup+Guide+Button&utm_campaign=WP
