Lately, the Single green light on my first-generation square reader does not go on. It used to work. Sometimes it successfully processes the purchase and sometimes it doesn't. What's is going on with my square reader?

Hi @Pegasus-pc 👋 thanks for flagging this. 

The following steps usually resolve the issue you are experiencing: 

Ensure both your Square Point of Sale app and mobile device are both running the most recent software versions. 

Open Square Point of Sale App: 

1) Settings > Hardware > Card Readers > Forget all card readers

2. Force-quit Square Point of Sale App

3. Open device settings 

4. Navigate to Bluetooth

5. Forget all Square Readers

6. Hold the button on the Reader until the lights flash red

7. Reboot the Device

8. Re-launch Square Point of Sale app, wait 1-2 minutes, and re-pair the Reader. 

Let me know the lights come back after trying these steps.
