Sorry to hear about the trouble. I would suggest looking into the updates on your hardware first. Most of these issues pop up due to updates that have not yet been installed.
You should be running iOS version 12.3 (just released), and Square App version 5.12.
If are updated and are still having difficulties, this troubleshooting guide may help. Also feel free to reach out to our Customer Success team if these steps don't solve the issue.
