Unable to search using app

I am new to Volumio. After installation on a RPi I thought I had found the perfect portable solution for taking all my high res music travelling with me, until I tried using the volumio app or the web UI. Searching and scrolling is painful no matter how I try it (artist or USB folder etc).
Is this me or does it just not work? Any tips welcome please.

Details please. I have no problems searching; what is is that you are having problems doing?
