My iPhone Location Not Found on Find My After Drop

Last night, my iPhone slipped out of my pocket. I tried to locate it using the “Find My” feature by logging into iCloud from another phone, but it showed “Location Not Found.” I can still locate my Apple Watch and AirPods using “Find My,” but not my lost iPhone—even though the feature was enabled on the phone. When I contacted Apple Support, they assured me that “Find My” should work for up to 24 hours even if the phone is off. However, I haven’t received any updated location data and still can’t find my phone. I urgently need Apple’s help to track down my lost device. Please assist me as soon as possible.
