I have followed provided instructions to add the plugin/package to our handsets that need them to enable remote control. We have a mixture of handsets - the Samsung handsets work perfectly fine without a package deployed and I can see and control the phone through Remote Control. However, I have tested this on our Sony and Nokia handsets - I can see the screen but cannot control it. I have tested a Sony Xperia L3 running Android 8.1.0 and a Nokia 5 running Android 9. I downloaded the packages from the SOTI website - have I missed a step that allows control of the phone?
