I think you have to wait for Touch able to be optimised for Ableton 11. They changed how control scripts are implemented. So all the controller using custom scripts need to be updated.
we are still working on a proper solution for Live11. The scripts are working, but the message handling on script side completely changed. Currently all messages send from touchable to Live have a huge delay.
I just bought Touchable Pro last night and updated Ableton Live from V10.x to V11 a couple days ago. My Ableton is on Windows 10 laptop. Got it working with V10.x but V11 has issues as discussed in this thread. Thanks for working to support V11, I’ll be anxiously awaiting new version and happy to test.
