I had it in November and then it just disappeared

I had it in November and then it just disappeared and I was not able to download it after. Seems to be a glitch with the connectivity with Samsung. I worked with someone at Samsung directly and I had to reset my Smart Hub and I still could not get UF. He had me go to Google Play and try to download it that way, but it says that it is already installed because I have it installed on my Samsung phones. I have 3 Samsung phones with UF and after I uninstalled it on my phones, it would still not allow me to install on my TV and only gave me the option to install on my 3 phones through a dropbox. When I look for UF through the Smart Hub app search, I only get Youtube that has UF videos. Have been very frustrated because I have over 70 movies. I just need some time to sit down and work with support I guess.
