I do have a mesh of 6x deco xe75 pro. 4 of them are v1 fw 1.4.1 and 2 of them are v2 1.2.11. 

I have two major issues:

1) using iOS Deco app it is showing incorrect info showing some of the wireless clients it is showing as connected by ethernet. How this can be fixed? 

2) 2 of the deco xe75 fw 1.2.11 are dropping from mesh network constantly (on daily basis). Connected by ethernet backhoul it is showing as "Offline" in the iOS app but the led on device is showing green fine. if I try to use ethernet ports from the same device I do get IP as expected and everything works despite not displaying correctly.

Is it possible to see dhcp leases? Is it possible to clear app data to show correctly?
