Sure thing! The RPi4 is running a pre-existing application, so I can try building the project on a new application and see if that works. I’ll be able to check that in a couple hours.
I was able to get the Pi to connect over WiFi again after starting the device while plugged in to Ethernet, then unplugging Ethernet after a few minutes. Because of this symptom, I’m beginning to think that the issue may be my own WiFi connection, but the problem is seen across three separate networks.
In order to replicate the issue, I simply went to my Application, clicked Add Device, selected Pi 4 64-bit BETA, and flashed the image via Etcher.
Here is a link to the device, with Support Access granted for 1 week: proud-forest
EDIT: More info on WiFi-Connect. The container launches just fine, but will not create a wireless connection. Because of this, I can’t connect to it and specify a new WiFi network to connect to.
