NEwbie in need of help

HI guys, I’m a complete newbie to all of this and I’m having some trouble. I’ve successfully installed Lodi to my newly purchased fire stick and have tried to install now four different streaming add one, including YouTube, the first 3 despite been popular add ons, once I installed do not appear to have any content at all to them, the YouTube one at least does show titles of videos but again, will not stream once I click on them. I fear I am doing something wrong, any suggestions?

PS: I really am new to all this so please treat me as a simpleton when giving any advice lol. Thanks
