Hello together, I have been the owner of a V90 D4 since last November. I found something similar here, and tried the solution approaches, but without success. Remove mobile phone from the Sensus and reconnect, everything does not work. I own an IPhone XS, at the beginning when I had paired the phone, I can be mistaken because I did not check it, all contacts to the Sensus were transferred. At some point my son who starts with M disappeared from these contacts. My daughter who also starts with M was still present. I have caller pictures with my wife and my children. My wife starts with L, her picture was and is available. My daughter was only about half to see and my house, that I also have as a caller image is only to see 1/4. Meanwhile my daughter has also disappeared from the contacts and only a small part of the name stored with M has been present. Now it is even so that all contacts from the letter N have disappeared! I was already at the ?, who could not tell me a solution. Does anyone know this problem?
