BTT is does not start after wake from sleep or login

Just updated to Mojave yesterday. Since then, BTT does not load on touchbar after all wakes from sleep. I have to manually "Restart BTT" to trigger it back.

Any help on that?

There is an issue for this here: After sleep, global touchbar widgets are not visible

I'm still trying to figure out what causes this on some systems - let's continue the discussion there.
