I never update anything unless the thing in question provides security (windows for example) or it’s currently not operating optimally, or the update provides improved functionality (but depending on how much I want whatever is being added, I might wait a while for the update so as to find out if other users have a problem).
With my kickr bike I check everyday for a new firmware update because the firmware currently sucks. With my tacx neo, I applied one update and it was to get road feel.
