Smarters player on Firestick showing black screen with audio on some shows

by QwertyVirtuoso

I've been watching a (non live) show via IPTV using the Smarters player on my Samsung TV via my Firestick 4k.
Some episodes only play a black screen but with the audio running.
It's also intermittent as I jump ahead a few episodes to test and they play fine but when I come back to the same episodes they just show a black screen also.
I've tried re starting my router and also my Firestick as well as doing a force stop on the app and deleting the cache but I still get the black screen.
Any tips?
