I've noticed when using Logi Flow that it can take a few seconds before copying a string (like an URL) from one machine to the other before the value is actually available. As a user you have to look carefully because you copy a URL, move to the other machine (I have configured CRTL + moving to side of screen) and paste the value. At many occasions you basically pasting "old" information from clipboard as the just copied data has not arrived yep on the machine. Both machines are connected via wires to the same network switch so I don't see how this can be the issue.
