Newsly Added Domain not working

Hello,

i added new domain name to my existing domain that is bolly2tolly.net (primary Domain) New domain name bolly2tolly.co (newly added Domain) via cname pointing.

https://prnt.sc/q8l5u8

now the problem is new domain is not fully added to my wordpress, when i access it through bolly2tolly.co it is redirecting to .net and content of my net domain is showing up .co link on my site.

please see this

https://www.bolly2tolly.net/movie/jumanji-the-next-level-2019-hd (Primary Ddomain)

https://www.bolly2tolly.co/movie/jumanji-the-next-level-2019-hd (Cache problem)

please try to access other site content through bolly2tolly.co domain, all site has .net links only. can’t access any content inside my site with .co links.

how to use both .net and .co links on my site, if user want’s to use only one domain.
