I went, to Spacedesk after the App Store, on windows 10. Then, installed everything, including access, to Firewall. However, my RCA Voyager, which uses Android version 8.1.0, cannot install, (or can I?), install more than the google play store app. This app was install and it asked for the IP address, which I found, on my windows Spacedesk Viewer app. I typed it in and pressed add, but after an hour, of waiting, for the connection, it did not work.
I'm guessing it is the android version! If not what do you suggest as a resolution? Thank you
