Say I haven’t got an internet connection… I can test that by… not having an internet connection.

If I open my App, does it show anything? Does it work?

PWAs do. That’s a key feature.

Say you are in the middle of using one of our apps and get on a plane. The app works in flight mode, and when you land your data gets synced as soon as normal connection is resumed.

The user shouldn’t even notice unless the try to load new data and if they do they are politely informed of the lack of connectivity in a way which isn’t intrusive and can be turned off
