5008 SUV – problems with MirrorLink

Hello together! I’m new here and I’m not sure if I’m right here with my problem (otherwise please move). 2 weeks ago I got the new 5008 SUV. This is equipped with MirrorLink. I own the Galaxy S7 on the other hand. AndroidCar I tried out and this works very well, but is not what I want. I would like to mirror the complete mobile phone (that’s why I absolutely wanted MirrorLink). After days of searching the Internet and i n forums I have it now that my system in the car recognizes the LG MirrorDrive and I can see something with it. BUT: I see only the upper half of the mobile phone (mobile phone is high edge and display in the car crosswise – I already had an app on the mobile phone where I could tilt the homesreen, but still the lower part of the mobile phone is missing). If I then click on an app I always get the message that the app is not compatible with MirrorLink. Then I click again the LG MirrorDrive But after every click/action I have to do it again. That can’t be the solution. What am I doing wrong? Thank you for your help.
