No, only people with the WD mark next to their user name are WD employees.
If you’re using the Media Server option, then it’s the SERVER’S job to update the data, not the WD’s. The WD can only display / play what the server tells it to display. You can check your server’s manual for instructions to force it to update its catalog.
I would recommend you try connecting your external disk directly to the WD and see if it has the same issue with your audio files cutting in / out… If not, you know it’s not the WD doing it…
As far as feedback / improvements are concerned, you can try contacting technical support. However, it is doubtful any “improvements” will be made as this product is no longer being developed.
