Thank you for replying. I don't use root, I just unlocked bootloader and installed the rom via adb. Could that be the reason? :( I have no idea how to root and I'm afraid I won't be able to use banking apps or other problems in the future
Oh my god I think that's my problem. After opening bootloader and installing the rom, my WhatsApp shows a message that I need to install the official version of WhatsApp. I thought that everything came from using WhatsApp plus in the past, and by using "mi mover" to copy all the data from Mi 10...
