Ok, the issue why you are having problems downloading the firmware is because you have a collective of 1. That is something that is an overkill since a collective is only for more than one devices. On the old version of the app we do warn you not to create a collective of one and on the new app, it is something we do not allow.
In this case, we will need to destroy your collective, then restore your settings into the individual device, and then update the settings. Once you remove the device from a collective of one, you will be able to update without any problems.
Please submit a ticket at
CoralVue Support Portal and tomorrow we will help you with the process. We will get you updated in no time. We just need to follow the steps in the correct order.
