Devapp losing connection to server?

Hey guys,

Is anyone else seeing this:

I connect my iPhone 8 Plus running iOS 11 to a local computer running ionic serve and everything is wonderful. But if the phone goes to sleep and I have to wake it, the DevApp is still running but suddenly is no longer connected to the server, or at least that’s the way it looks - the app(s) that my phone could see before sleeping aren’t there anymore. I have to kill the DevApp and then relaunch it to see the same apps I could see earlier.
