If I do the following on my iPad Pro 11 inch:Turn off Wifi and turn on airplane modeOpen our iOS PWAIt says “Safari cannot open the page “http://www.example.com” because your iPad is not connected to the internet.”If I then turn on Wifi and turn off airplane mode, it still has the same message.If I force-close the iOS app and open it again it still has the same message.If I delete the PWA and reinstall it then the message goes away.Or if I shut down the iPad and restart it, the message goes away.I don’t have any PWA service workers and haven’t really looked into what they are and what is needed. Do I need to have one to eliminate the behaviour described? And if so, what should it be?
