@xplodzs I have a newer beta firmware that support gave me: 1.6.7 build 20250807 Rel. 56374. It seems to have fixed the issue. My devices are properly showing upwards of 63+ devices where 50-59 are...

@David-TP 1.6.6 didnt fix the issue but 1.6.7 supplied by support did.

@mmir DoT works as expected and allows custom private DNS servers. Use the DoT address from ControlD dashboard endpoint and it will work fine. I use it this way for now.
