Google's Find My Device network might get an automatic opt-in boost
Enabling location services could opt you in

Google's crowdsourced Find My Device network has been a bit of a letdown so far. Even though we've seen some significant improvements lately, the fact that devices only contribute location data "With network in high traffic areas" by default instead of "With network in all areas" means that there are plenty of places on the map where a lost device likely won't be found. Google isn't changing this yet, but it appears to be making some tweaks to how phones and tablets are opted into the network.
