Arp Shop review for Facebook & Instagram

Hi, i have a big problem with this app. Whit this app my FBpixel collect events only if my shop is setting on the defaul domain. If I set the shop to use my own activity domain (a third party domain), the pixel stop collect event. Anyone can help me? I tried to install/reinstall/clean business manager/verify domain/eliminate cookie banner. Nothing worked. I'm disheartened.
