Both GPS drop in Use Best mode

Hi all,
Been trying to lab test the functionality of the Use Best mode (using the mRo Location One, both connected via UAVCAN) - by disconnecting 1 unit and see if the other one takes command.
What’s we’ve observed was a drop in sats for both for several seconds.
Tested on an mRo Zero F7, V4.0.0
