Resolve Live Replay not working with HyperDeck NAS recording

I record with a HyperDeck 4K, latest 4.8.1 firmware, to a Synology NAS by SMB.
When I open DaVinci Resolve Studio 19 Public Beta 6 and import the files they are not recognized as growing files (they just import to the point of the import time) also the Broadcast workspace (as seen in some demo video) is not available.
The replay tab is there but cueing does not really work.
Is Resolve live replay currently only possible when recording on a BM Cloud Store product or should it work with any HyperDeck SMB NAS recording on any NAS?
Replay is also not listed on the BM Cloud Pod and Cloud Dock pages.
Or did I miss something?
