I have just today posted info about failing flow option with 7 of 10 times causing issues with leaving one device and moving other one...
So I have fixed it, one of messages was saying ABOUT vpn which ofcourse is used on one of the device. SO I installed with admin user privilages with vpn turned on (made it on hold when instalation wanted to connect for download) than turned it on.
After install I have turned on Logi+ as admin user (vpn turned on) configure it, now it works perfectly but - I didnt yet restardted computer with vpn so keep fingers crossed. IMPORTANT - I use logidongles on both devices no bluetooth in use
