All my contacts have disappeared. What should I do?
You may have signed in under a different account (you previously used an ICQ account, but you have signed in using a new phone account). Be sure that you have signed in using your account:
- Go to your profile
- Compare the UIN in the profile with your UIN
If the UINs do not match, tap the "Sign out" button and sign in under the correct account using your UIN/password.
