Using DuneHD Internal Hard Drive as record location for HDHomerun network tuner

[EditBear]

Hi,

I'm very new to the Android TV box scene having jumped ship from Mediaportal on PC.

I have installed the HDHomerun Android App from the Google Store & purchased their DVR licence.

I have formatted a 2TB SSD in the Dune tray in both NTFS and exFat but HDHomerun does not see it for recording?

The Android version of the HDHomerun app should have integrated network record setup software for certified Android devices according to this link;

Can you tell me if the DuneHD pro 4k plus 2 is certified in the way they expect (such as Nvidia Shield)?
Or what I am doing wrong?
