I have an odd issue with internet connectivity and my (2018) iPad Pro. Here’s what happens:

1. Plug in Apple’s USB-C Digital AV Multiport Adapter, and plug in a USB mechanical keyboard (tested with three different ones, same behavior).
2. Work.
3. At some point while connected to WiFi still, the internet stops working.

The only fix is to unplug the adapter and things go back to working within a few seconds. Even toggling WiFi does nothing. Anyone else have this issue?
