I already used the old version and it has already been deactivated, I registered in the new version, and is informing that the unit (imei) is already being used. What procedure?
It looks like your account has been migrated to the new version.
You can try to login into new platform using your old username.
If you have faced with some issues, try to reset password by this link
So I am right to understand I continue to use orange until I get notified my account migrates? Or should I migrate myself manually?
If you get login error in new version, use registration.
I registered new account, I cannot add the device due to Entity unit (id=437847) is already use.
The problem is fixed
