Good morning from Greece. I have the vu + duo 4k receiver and I would like if I am allowed to ask two questions: a. I can no longer connect through the vu + HD Payer application that I download from the Google play store on my Android mobile phone or tablet. I have to say that I put the nternet address correctly, but I keep getting it wrong. Until recently I was connecting normally. b. Is there a way to add an additional Greek subtitle finder to the receiver menu? PS: The receiver's operating system is black Hole, and it is connected with an ethernet cable. Thank you..
