I was using Triggers to reset the window position of my browser everytime I start it. Now it only works for one time after I save the triggers in DisplayFusion. After that the triggers won't work anymore until I manually save the list of triggers again.

I'm not sure when this began. Perhaps after the Windows Update to 1903.

It makes no difference to change the frequency to always or raise the delay. This settings did work before but now only one time after I click on Apply again.

I have deleted everything and did a new clean install without importing my old settings and now everything works fine again.
Sorry for wasting your time - I should have done this before posting here
