Disconnect within an hour every time, fixed by close and re-open

[nhooey]

ChitChat is disconnecting from WhatsApp within an hour every time I open the application, and never reconnects during the instance of the application.

Once I close and re-open the app, it works every time for a few minutes, up to about an hour.

I haven't noticed if there's a pattern to the amount of time that it stays connected.

This occurs with:

• ChitChat 1.5.0
• macOS Sierra 10.12.4
• WhatsApp 2.17.11, iOS
• iOS 10.2.1 (14D27) on iPhone 5s

This has only been tested on and occurs with the same local wifi connection, for maybe the past 3 weeks. It used to work without issue. Updates have been configured to install automatically on my Mac and iPhone, I haven't payed attention to what was installed over the last 3 weeks.

What sort of troubleshooting should I do?
