Can't help with the problem on your specific TV and I assume you've checked the manual for how to update the app store but others have ran into issues with apps being buggy or simply not available for their smart TV brand or model.
The easiest way to get up and running is to buy a Roku Express 4K streaming player at Walmart for $29 with voice control and plug it into the HDMI port of your TV and use it instead for your streaming. You'll be watching in minutes and there is no monthly fee, just the initial cost of the device. I think I posted a video previously about how to set it up.
