Hello @Andrea_Hopkins,
As a general rule, it is normally recommended to make any dashboard configuration changes during downtime or in a maintenance window. If any unanticipated issues arise as a result of the change, it will not affect live production and can be reverted without significant impact. Additionally, if the changes are being made on a specific model device like the MX84, it is a known unresolved issue that a brief period of packet loss may occur when a configuration change is made on the appliance, as seen in the firmware change log below:

Best,
