Can't Load folders and tracks change BPM without warning

I have been using djay app for iPad for about 10months now without any problems. However when the recent update cam through I could no longer load any folders with music which I had been previously been able to do. Also Mysteriously the BPM analyser is not accurate. At times it changes the BPM without me controlling it. I have a Pr account and I am running 5.0.1 and my iPad is running OS 16.7.2
Can you help?
