Streaming, downloading and what you can take offline
The difference between a service that streams and one that gives you files, and why it matters on a train.

Streaming is the default
InstantApps runs in the browser. The content plays from the service rather than being copied to your machine, which is what makes it work on any computer you happen to be sitting at without installing anything first.
The cost of that is a dependency on your connection. A streaming service is only as good as the line it arrives on, and no amount of subscription solves a bad one.
Downloading
The published material describes streaming and downloading on computer, tablet and phone. What it does not say - and what we are not going to guess at - is which content can be taken offline. In services of this shape it is usually some of it rather than all of it, and it varies by content type and sometimes by individual title.
If offline use is the reason you are subscribing - a commute without signal, a flight, a place with bad coverage - test exactly that during the three days. Download the specific kind of thing you need, put the device in aeroplane mode, and see whether it plays.
Downloaded is still not owned
Even where a download works, it is access rather than a purchase. Content obtained through a subscription stops being available when the subscription ends. Nothing here becomes a file you keep and can move to another device years later.
Practical things that help
- Test on the connection you will really use, not on your home wifi. A service that is fine on a fast line can be unusable on a phone in a basement.
- Check the quality settings if there is a choice. Lower quality uses less data, which matters on a metered connection.
- Watch your data allowance. Video is by far the heaviest of the seven libraries. An evening of streaming on a mobile plan can cost more than the subscription does.
