Troubleshooting ARC
Start with the least disruptive checks. Avoid repeated resets or account changes unless the production support flow specifically calls for them.

Check fit and cleanliness
Make sure the sensor surface is clean, dry and sitting flat against the skin.
Check the phone connection
Keep ARC close to the phone, open the ARC app and confirm that Bluetooth access is enabled.
Check the network
If account data or cloud-backed features are not updating, confirm that the phone has internet access.
Restart the app before removing the device
Closing and reopening the ARC app is less disruptive than unpairing the band or clearing app data.
Capture useful details
If the problem continues, note what you expected, what happened, when it started, the phone model and operating-system version. Screenshots can help when they do not expose private credentials.
