Hello,
I checked for example about us page and it has the correct index meta https://prnt.sc/26twbb9
Our theme does not have any limits for indexing.
So, read this post https://www.curiousants.com/game-plan/technical-seo/google-search-console-coverage-excluded/ and check if you have anything of that.
Also, we would recommend to create the correct robots.txt file and try to force index some pages.
