A macro must be enabled for it to be triggered. If it is disabled, it will not run no matter what the trigger is.
You can enable or disable macros by selecting them and clicking the ✓ button at the bottom of the Macro column, or by editing it and ensuring the button at the top right corner shows a tick.
If the macro is disabled, it will also show dimmed in the Macro column.
Remember that the Macro Group must also be enabled and active for the macro to be triggered.
If you continue to have problems, contact support.
