Hello all, does anyone know how to get Red Box TV installed on their fire stick? Many thanks

Looks like there may be issues with Redbox.
However, this may or may not help:

Just checked my own Redbox on my phone....not working.

You can download Filelinked app and use code 22222222 for alternatives.

Redbox has become very hit and miss.
Here's how to put it on Firestick though.

That's great, thanks for your help IanMCL and Buxton

Try TV tap pro for fire stick which I have found more reliable and mine is 1st generation fire stick.
