Hi ! I totally agree, I'm using the paid version and I will continue to use it, but the new UI is really not nice. Usually I love when it changes but here, it's like a cheap Adaware software with these big buttons and this enormous Police (wich is really not modern). The scan/detection history/live protections icons look also really cheap and not modern at all. For me it's like a software from 2016, not 2020, I advice you to change it in a way more modern and professional, like the old UI. For me you should remove the background image, and all the shadows, and you should also reduce the size of the police, really.
Finally, the little blue buttons (on/off buttons) are blurry, hope you will fix it !
