Account linking on Polaroid Smart Tv not working

My polaroid TV has the deezer app and ive been trying to log in. but the QR code or the link leads me to a deezer website but keeps on asking to continue to the deezer app so I pressed it and theres no place on the app where I can link my account. I need help trying to do this? how do I fix it? where do I put the code on the app?
