Why did I start getting 403 codes returned from the AirBop servers?
If you were previously successfully registering devices with AirBop, and are now getting 403 error codes when posting to the server, this is most likely a result of hitting the device registration limit for your subscription level.
If you want to increase the number of devices that can be registered to your account you will need to upgrade to another account level. This can be done on the Plans & Billing page page.
Note: You should have received an email from AirBop when the number of devices in your plan hit 80%.
