Thinking about joining HBO soon. We are Amazon Prime members and want all HBO TV live shows just like we had with our DISH Hopper if there is such a thing. When I check my Amazon Prime account it says HBO Go and HBO Now are free download apps. Which one should I get for all live TV programs or is there another HBO app version I should get? Why are they free? I thought you have to pay $15.00 for the HBO app. Also, there is a choice to download to my 4K Fire Stick or the Cloud. Which one should I do? If I want to watch HBO thru my LG TV Amazon Prime Video app, will it work or do I have to always use the Fire Stick HBO app? Sorry if all my questions have already been covered someplace else. I am still learning all this streaming stuff. Thanks for any help.
