STV player wont work on my Formuler z7+

I installed STV and ITV player on my box, but getting a notice saying they may not work. and they don't. Anyway round this, I have a Panasonic TV and ITV player now longer works on it either.

ITV Player dont work on most devices. Not sure on a fix for this or work around. maybe try different apk files from Aptoide, APKpure
