I am not able to get this software scrub clipboard text at all. My setup somehow stopped working and now I am stuck, tried different settings for this but no luck.

this one seems to work now..
But what's the proper way to scrub text and also remove empty new lines

I have set settings just like you have there. and it doesn't work for me. why does it say "no" for "trigger command received" this setup that you showed simply doesn't work for me. even after I restarted the program.
