Owch thats not a good problem to have, odd its taking everything offline though you should only lose management access with your dashboard reporting an issue with the device.    The other option would be do you need to use Umbrella with your switches or could you use something else like Google.

Yes I believe you are correct.  If you flows are purely internet based you can define the "match filter" and route traffic over your preferred uplink. Flow Preferences By default (without load balancing), internet-bound traffic will flow out of the MX's primary uplink. The MX can also be configured to send traffic out of a specific interface based on the traffic type (policy-based routing), or based on the link quality of each uplink (performance-based routing). Flow preferences can be configured to define which uplink a given flow should use. Flow preferences will also supersede load balancing decisions.    https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/MX_Load_Balancing_and_Flow_Preferences   ...
