The destination can be right while the action is wrong
Imagine moving from a work computer to a personal Mac and pressing the key you normally use for a task. The keyboard may be sending input to the intended computer while the resulting action still surprises you. This is a different problem from a wrong channel. Before replacing a working pairing, identify whether the complaint concerns the destination, a printed symbol, an F-row action or a particular application shortcut.
Read the target system before the key legend
The MX Keys Mini setup guide explains its combined legends: Windows, Linux and Android users read the relevant characters on the right, while macOS and iOS users read those on the left. This is model guidance for interpreting the pictured keys, not evidence that every regional physical layout is identical. Keep a short note identifying the target system when comparing a familiar symbol with what appears on screen.
The F-row has another choice of behaviour
The same guide says the default is direct access to media keys and describes Fn plus Esc as the way to swap media-key and F-key access. That is an actionable distinction for someone expecting an F-key command. Check the documented mode before describing the channel as broken. Do not assume the same visible key invokes the same command in every application, or that changing this mode makes an unsupported shortcut available.
Test one transition with one real task
Choose a harmless task on each computer, such as a command in an empty document. Record which system is selected, which key behaviour is expected and what actually happens. Change one relevant setting at a time. Logitech also describes optional Fn customisation through Options+, but its software and platform requirements are a separate check. A managed work computer may not permit that software, so a plan depending on customisation needs permission before it becomes your routine.
Choose a shared routine you can explain
A person using ordinary typing across systems may be satisfied with the combined legends and a known F-row mode. Someone relying on different application shortcuts throughout the day should check those transitions before committing to one shared keyboard. Separate keyboards can remain a reasonable alternative when the required routine is too confusing. Keep only the system and key-behaviour notes that answer the observed problem; a longer channel map will not solve a mismatch between the command you expect and the mode you are using.
