Hey @allin1.kus.bd ,
Thanks for your commentary here!
This feature “remove unused css” can’t be used anymore because the css goes to their servers. On their servers, we can’t edit any code to activate or to solve this.
To be honest, I think it is fair from their side since this feature does costs them money to maintain the servers and fix the bugs.
If you need this feature, I would recommending purchasing directly from the developers.
