Why Don’t Streaming Services Allow Downloads On More Devices?

In our house, everything we watch is via streaming services. And we’ve got a couple of young kids who like to watch the same shows again, and again (and again!) - luckily we all enjoy Bluey 😅

We use my Xbox as our primary streaming device, with the native apps for each service we subscribe, but this applies to any streaming box:

Why can’t we download content for “offline” viewing on streaming devices like we can on our mobile devices?

It’s a waste of bandwidth and energy if you want to stream the same content multiple times. For us as users, it would be more convenient and reduce our energy usage. I’ve got to believe that this would also be of benefit to the services themselves, reducing their operating costs because they don’t need to pay to stream 4K video to us unnecessarily when I want to watch Across The Spider-Verse a couple more times.

The streaming device, my Xbox in this case, is always connected to the internet, so DRM isn’t really and issue. I can understand (to a degree) not allowing offline viewing with web browsers, but in their native apps on a streaming device, why is it different to the mobile experience?

Most streaming devices have a reasonable amount of internal storage, so that shouldn’t be a barrier either. Maybe no-one’s ever asked for the capability?

I wonder how many other people are in a similar situation to us. Our percentage of re-watching things is much higher than first-time views. We like what we like. It would be nice to do it in a more sustainable way.
