Smart View connects to TV but immediately stopped displaying video/audio after installing the Dec 2019 phone update.  (G970U1UEU2CSKP)  I show a Jan 2020 update pending and intend to install it when I have access to a wireless network. Will see if that changes anything, but not hopeful. Do not have a different phone i can test. Would like to avoid wiping & reinstalling the phone or TV - been there, done that before.

My best cell signal is 1-2 bars 4G LTE about 15 ft from the TV (-114 dBm on a good day) My options appear to be:

1. A 16'+ HDMI/USB-C cable from phone to TV cable (clunky, but good video/audio on shorter cables I've used in the past w other TVs)

2. Chromecast HBO NOW / YouTube and hoover my hotspot data. (great video/audio quality)

3. Google Home mirroring of phone. This works for YouTube but HBO NOW is blocking content over that connection. Uses hotspot too, so unsure the data hit this entails. Less than Chromecast?

4. Smart View gets fixed or figured out. Video quality via Smart View is as good as the cell data speed allows, but audio is sketchy regardless of connection or content being mirrored. All apps including HBO work via that connection.
