Hello!
I have a JOYING 13.3 Inch Double Din Car Stereo Qualcomm Snapdragon 8+128GB and downloaded the Qualcomm version of the launcher. Everything works great, however when I use the PIP, the apps don't seem to fill out the space. A black box always appears at the bottom of the smaller of the two apps. When you use the slider, the black box shows under both. When I open the app in pip it works for a second but then it looks like the app switches orientation and then the black box appears. Let me know if i can provide anything else!
