I have a Verizon 5G Ultimate home internet system. I purchased the Deco BE 5000 3 pack mesh system due to significant buffering issues.  I worked through the installation of the mesh system to the point of connecting one of the mesh components to my internet.  However, when the Deco app informed me to plug in the other two units all three of them progressed to the point of a sold green light meaning a firmware upgrade is taking place.  I have been waiting several hours and all three units are still solid green.  Does anyone have ideas how to get past this stage in the implementation?
