get_playback_files not working?

[trapexit]

Using Python 3.12.9, reolinkapi 0.4.1.

I've tried Camera.get_playback_files(start=dt.now() - timedelta(days=1)) on a E1 Zoom, E1 Outdoor, E1 Outdoor Pro, E1 Outdoor CX, RLC-523WA, and RLC-823S1W and they all return an empty list. They all of sd cards in them and show recordings over the previous day.

I've tried with streamtype='main' and changing channels but no difference. Always empty lists are returned.

I tried for hours how to download all videos from one complete day with this api. It didn’t work because of get_playback_files.
Now I’m using the Reolink Desktop Client from https://reolink.com/software-and-manual/ that I never heard before.
