Great App but Pro is not working – djay - DJ App & AI Mixer Review

So I just purchased pro to work on my music and whenever I try to use the instrumental feature or vocal feature it just stops and won’t do anything. I’ve tried resetting it but it still doesn’t work and I don’t want to have to pay 6.99 if it doesn’t do me anything the original version can’t do
