The phone number in My Avast account is incorrect and I can't change it. I can enter the correct number and save it, but the update is not effective, the original number is still displayed when I go back into the setting.
I tried deleting the device, uninstalling Anti-theft and antivirus from the phone, then reinstalling, but the old number is still used in my account without me entering it.
The impact of this is that the remote anti-theft functions cannot be activated if mobile data and Wi-Fi are switched off on the phone. It cannot be contacted using the mobile number alone to send SMS commands.
