Robohelp 2019 training in UK?

Hi

Can anyone recommend a training provider in the UK that can go beyond an introduction to and/or the basics of RoboHelp 2019? I have used the 2015 and 2017 versions, learning on the fly and feel that there must be so much that will help with efficiency if I could sit down with someone.

Failing any providers, is there any online material beyond the TechTools course available?

Thanks 

Richard
