Yesterday I installed EU rom on my F6 device. WhatsApp shows the error "You need official WhatsApp to log in" both when models are installed and not installed. I tried many modules including Tricky Store but I couldn't solve it. I can use WhatsApp without any problems with classic modules in Indonesia rom. I got the WhatsApp error on my old device, X3 Pro, with EU rom installed. Is there a other way to solve this because I want to use EU rom due to the restrictions of stock roms.
