Ring Door bell

Ok I have had a ring Door Bell for about 1 year now. I had it working with my Echo Dot and Amazon Fire Tablet 10HD. So when someone came to my door and rang the door bell, Alexa would announce someone was at my front door and it would also broadcast the video on my Fire tablet that I had mounted on the wall. When there was no video being broadcast my Tablet would have the time, two week calendar and five day weather forecast showing on it. Now for some reason it no longer works. Fire tablet works fine but when someone comes to my door and rings the door bell, Alexa still notifies me but the video stream will not come up on my Fire Tablet. I have tried everything to fix it including deleting everything and downing loading all new apps and resetting it all up and still nothing. I do have a fire stick on one of my TVs and it will work with that but I don't want it on my TV. So is there something else I can do. Is there something I can buy, mount it on my wall and have the same setup as I did with my Fire tablet? I also have some Lorex security cameras that are hooked up with Alexa and when I ask Alexa to show me the cameras it will show them on my TV through the fire stick but not on my Fire tablet Thanks Bruce
