Hi, I have a mangOH red board. I have checked that the device is connected to the 2G GSM network, AirVantage shows the data usage when I ping websites. When following instructions for the Starter Guide the redSensorToCloud app is [running]. However, when I look at the AirVantage dashboard no data is transmitted , the “Last Communication” section says “No Usage”. When running diagnostics on AirVantage, it says the problem could be incorrect APN or IP address. I am using the APN [internet.sierrawireless.com](http://internet.sierrawireless.com). Could that be incorrect? What could be the reason for this?

PS. I am in Canada, where the LTE Cat-M1 network is not up yet, but I don’t think that is the issue because I am on the 2G network.
