Android app not working?

I just joined Zwift this week, running it on my Pixel 3. I took two rides earlier this week without issues. Today, every time I actually load into the world, I'm underneath it. I can't move, and all of my sensors show 0 even though they were working on the connection screen. I tried all of the available worlds, plus a reboot of my device. Other 3D games still run fine. Totally out of options other than buying a PC.
