Synology’s DS CAM had an update recently, and the new version: 5.10.0-1331. Breaks the ‘Camera Info display’ option on the Multi-View screen.
I’ve been alerting Support about this, and after a few false starts, today they reported that they have reproduced the issue as I reported it, and DS CAM update broke Camera Info Display in Multi-View with the newer version, and they are reporting to the software guys for a repair.
Unknown time frame for repair.
