The desktop app board "copy board link to clipboard” shortcut is Ctrl/Cmd-Shift-L, which is the same as Lock.
So, what this means is, when using the Miro desktop app, if I have something in my clipboard that I want to use later during my board session, when I Ctrl-Shift-L to lock an object, Miro is overriding my clipboard with the board link/URL.
Please change the board link shortcut in the desktop app.
