I deleted after a few test runs. @Fiorot is right. It keeps opening my browser for ads and i finally saw the girls ass he was talking about. Took long enough! 
Streamfire/Sportsfire are much better in my opinion as a stand alone app. Plus many other ways (kodi, tvapp etc) without the hassle.
I had RB working great and today when I tried to use it I got this chick with her ass in my face. Any suggestions other than lucky you. LOL. I have to go back to my home screen because it locks up the screen.
i just now reinstalled it and it is okay now. The lady with her ass stuck in my face has wwnt bye, bye.
Agree adds nightmare I deleted it
Did it (the ass shot) come back? It did on mine. It goes away for a while, but then it comes back.
Wifey says WTH is that and I said, “I found an old shot of you, darling. I needed the memory”! 
Thanks Miki… I’ve been seeing the TDUK thread, but I think I read where it only works for 6 or 7 days and I guess it’s kinda beta at this point? I also read where TDUK said it would eventually be available on the Play Store and just figured I would wait for that.
Sure thing @JDMotes. I don’t think it will be long. About $2 USD for lifetime I think.
I got rid of it. Not worth the space on my firestick.
I downloaded this my firestick 4k and when I tried to open - I received the message to install the update. The problem is I am not able to highlight any option to update. Anybody have a fix?
Having followed the instruction from Troy to install, I found that each time I click on a particular game I get a Porn picture/video !! I’ve uninstalled, reinstalled a number of times and get the same! Anyone else suffering this or recommend how to stop it?? Not nice when my grandkids come to watch a game
I get the same , but uninstalling no matter how many times , it always comes back when I reinstall!!
The link above will give you new version 1.8.38
I’m not getting any porn ads at all on mine but there is an ad blocker on my Express VPN and I’ve got TDUK ad blocker on so one of them is stopping them.
PapaS, Thank you for the information, I am going to try it. By any chance can I get this using the Downloader?
Thank you again
Just type that URL into downloader should work 
Just tried it on my phone and if I type in cutt.ly/rbtvapk77
it works.
I typed in the download just as you stated ‘cut.tly/rbtvapk77’ and I received the error message "An unknown error has occurred. Check your URL and connection.
I took a screen shot of the Downloader and how I entered the URL, I don’t know if I can get the pic to you. I did try it on my cell phone and received an error message asking me if I didn’t me cuttly/rbtvapk77, I tried that and it went to that site/URL and gave me back No Results, and suggested that I search for
cuttly%2Frbtvabk77 on google (these messages were from Downloader)
You entered the URL incorrectly. It isn’t cut.tly it’s cutt.ly
I tried “cutt.ly/rbtvapk77” and it worked.
Thanks to everyone who gave me information to get the app.
My bad, I wrote it down wrong above, so I’ve edited it to show the correct one.
Thanks @Miki
I just went to this site “cutt.ly/rbtvapk77” and received an error message and could not go further. I have tried to search youtube trying to see if I could find rbtv77 v 1.8. Does anyone know where I can download this file?
Read the very first post in this thread by the site owner, Troy, and follow his instructions. See if that works for you.
