Parse Error on Firestick

Hello
I downloaded Blokada 5 from this site and it installed fine on my android phone but, when I try to download on my Firestick I get a parse error. I want to upgrade from 4, which I haven’t removed since it wasn’t necessary on my phone. Can you help me? Much appreciated.

Hi,
V5 isn’t optimized for Android TV devices
Please stick to V4 for now
