Hi there @MDTA, thanks for your post.

Just to confirm you are trying to connect a Square Reader to a mobile device?

First lets double check you are connecting to a supported device.

If you see the message that Developer options are not supported, please turn off the developer options within your device before running through the troubleshooting steps. To turn off developer options:

Navigate to Settings section of your device > Developer Options
Toggle Developer Options off.

If you can’t see the Developer Options menu:

Tap About Device
Tap Build Number 7 times > you will see a prompt on the screen indicating developer options are enabled
Tap the back arrow to navigate back to Settings
Tap Developer Options > toggle Developer Options OFF.

If you are using a Huawei device, you can also try:

Go to the Settings of your Huawei device
Tap on More Settings
Disable the button Allow Hisuite to use HDB.

After these steps you can try the try the troubleshooting steps outlined here.

These steps usually help getting the Reader connected (as long as your device is compatible), if it doesn't work the first time - usually waiting 30 mins and trying again will do the trick.
