mobile page view not showing actual theme

[ Moved to the Fixing WordPress sub-forum. ]

hello, I just decided to do self hosting blog with blue host, so I installed WordPress and ow I have a theme installed called RARA theme from KALON. well I installed it and everything seems to be ok, until I put my website address. https://www.anysblog.com on my social media accounts, when I clicked on, it takes me to my website but NOT the pretty one I created it, its just plain blue, I have to click “view mobile site” at the bottom of the page so I can see the website I created with the nice theme. is something wrong? I tried installing and installing the theme again and it still does the same.
Please help, I am NEW to this and not tech savvy at all, but wanted to start blogging.
thank you.
