There is a well-known bug in logi options+ that causes intermittent disconnections after waking PC's from sleep. Eg this is one of the many posts on the topic, where users ask if there is a fix: https://www.reddit.com/r/logitech/comments/yoh4ju/logi_options_flow_keeps_reconnecting/?utm_source=share&utm_medium=web2x&context=3

I posted a fix in that thread (https://www.reddit.com/r/logitech/comments/yoh4ju/comment/j46xwfh/?utm_source=share&utm_medium=web2x&context=3).

The fix could be simplified considerably Logi Option+ had an extra button on the Flow configuraiton page, "Restart Flow Agent". This would obviate the need for killing the Logi Agent process from Task Manager and waiting for Logi Option+ to ask if it should restart it.
