Now that I say that, I do remember connecting at home. Also, I can connect to the limited, “guest” network at work, so the WiFi is functional.
On that guest network, I am getting an error about an incomplete TLS handshake on the phone app upgrade. I also don’t see any other updates showing, even though the phone has been off any network for at least 4 months. Shouldn’t there be some other updates? That seems like a long time without improvements for a still-being-polished device. Did they quickly install in the background before I noticed?
