Late one evening my training app refused to pair with my watch, leaving last week’s runs unsynced and a race plan uncertain. Rather than chase random forum tips I exported diagnostic logs, recorded a short clip of the pairing attempt and uploaded everything through garmin support so the techs could reproduce the issue. A technician identified a corrupt Bluetooth cache, pushed a small app patch, cleared paired-device records remotely and guided a one-tap resync. Follow-up checks restored routes, splits and heart-rate files. In short: include logs, timestamps and a short video in the first message to speed diagnosis and avoid wasted retries.
