unable to attach - error - new Configurator w more bugs

I'd love advice from people who have tested MDM alternatives for a few months.

I've just updated to the newest configurator and it has more bugs than the "old" version. ipads constantly must have their screen touched to say "Trust". If I can't race to touch the screen of the ipad my mac shows this error when I connect the mac via USB to the ipad. This happens even with only one apple genuine USB cable attached. The error is: "unable to attach device to Apple Configuator"

Apple's confiturator is doomed, and it seems they want people to leave.

I do not want to use anything such as Apple's OSX server. I'd prefer some type of cloud tool or app that runs on a desktop mac.

Thanks for the help. Having ATTACHment issues.

ps: if it carries any weight, I authored this HOWTO document to help IT staff setup a cart with Configurator.
