I have a similar issue here. Trying to open an account with UK phone number but because I tried to open an account before with another phone number which did not successfully open an account because my country is not included. Now the app keeps asking me to log in with the old number with I no longer have access to. If I click “lost access to my number”, it requires 4 numbers passcodes which I have no idea what that is. Can you please contact me and sort it out? Thank you!
