Instinct 2x solar tactical not syncing after work outs

Hello, 

I'm sorry to hear you are having trouble with syncing. For this, there are a number of steps you can try, if this continues. 

Initially, I would just try powercycling the phone and hard reset on the watch. For this, hold the Control button until the watch shuts off, as opposed to selecting power off. Then power this on again. 

If there is no change, I would recommend syncing the watch with Garmin Express on a computer. https://www.garmin.com/en-US/software/express/windows/  This helps to determine if the sync issue is because of the phone pairing, or if this is because of a corrupted file on the watch:

• If this syncs with Express, likely a pairing issue. Use these steps to correct the pairing concern:
  1. Ensure the phone's OS is on the latest SW version
  2. Uninstall the Connect Mobile app
  3. Clear the phone cache and history
  4. Ensure the watch does not appear in the phone's Bluetooth menu. If it is, please remove the device
  5. Powercycle the watch and phone. To do this, hold the Light button until this shuts off. Then power on again
  6. Reinstall the Connect Mobile app
  7. Try the pairing again ( Be sure there are no other Bluetooth enabled device nearby)
• If this is also not syncing the activities with Express, this is likely one or more corrupted files. Use these steps to remove the stored files.
  1. Connect the watch with a Windows computer
  2. Open the watch drive
  3. Open the Garmin folder
  4. Delete the contents of these files: Activities, Courses, Workouts, Locations, Remotes SW, New Files
  5. Disconnect from the computer and powercycle the watch
  6. Try recording and saving a new activity on the watch 
  7. Sync this with Express or the app
