First problem is that after pairing, I can move the pointer onto the Android device but I can't move it back to the Windows 8.1 laptop. The arrangement appears to be correct and it does work as expected when moving pointer from PC to Android. Just can't go back. It's like a point Roach Motel. Pointers check in, but they can't check out. The second problem is that two finger scrolling on my PC touchpad doesn't scroll windows on my phone. I am using a Samsung S8 with Android 9 and a Samsung Dex docking station for the phone and a Samsung monitor connected to the Dex via HDMI. Also, after pairing, only my phone shows the pairing. The Across app on my PC doesn't show any pairing. Yet pointer and keyboard work on the phone.
