Prestashop 1.6.0.9 google seems to see ONLY my first page

[optionsmegastore]

hi all, after a long experience with prestashop and google indexing etc, i notice that google is indexing ONLY the first page in everything.

i rate good on google,my products get indexed within 24 hours anytime i add some, but it doesnt index more than first page.and since in prestashop the new products get  by default into the first page, then my life isnt so bad. 

for example 

products available in my 1st front page

products available in any specific category just the first page of it. and if i make some category load more of products, for ex 20 instead of 12, then these 20 get indexed. and quite fast yet the website turns slow.

any first page is indexed, categories/manufacturer/brands etc never the 2nd. i believe it's a prestashop problem but i can't get to solve it. please if anyone have any clue, i would be very thankful. 

btw i have 12 products per page

Any errors in google search console? Have you add site map to it?

Is there a sitemap.xml file being updated?  If not I'd consider looking for a module that does that or run a 3rd party sitemap tool and upload to site then resubmit to Google as an added push

yes there's a sitemap.xml updated . and i have google sitemap module also bing sitemaps and i generate them anytime i add new products.

look under pages in the GSC. There are your pages not index due to unfathomable reasons only Google knows.
Check there.
