Hi MagruderMan   We have just had the same error and it appears to happen when the username/password is not correct.  The enrolment process continues but it will fail with the "invalid device id or no pcc user" error as there is not associated user for the device in the meraki framework.   If you get this error:   Log onto the meraki admin console, find the device and you will find there is no user associated with the device.  "edit details"  add a user, go back to the device, open the meraki app, refresh the config and then add the afw account.   Hope this Helps!   ...

Hi Mark,   It looks like meraki has updated one of the packages required during the installation.  However, it looks like the haven't updated the checksum in the QR code to match the new apk files.   I had to:      create a new network      get the qr code       unencode that qr code with the correct checksum      unencode the old qr code/ get my meraki network id     put the correct network id with the correct checsum in a text string    use an online encoder to create the correct QR code.   I have raised a support ticket with meraki, found the problem and  then advised them, so hopefully they will fix it soon.   Good luck   Cheers,   Jay   ...
