I launched this app on my new Pixel 6 two days ago and took photos through the front-facing and rear-facing cameras. Sometime after completing the transfer of apps and data from my old Pixel 3, I got only a black screen, sometimes an error or app crash, the front-facing camera worked after some delay about 20% of the time. I've updated the OS and camera app, uninstalled recently added apps, tried safe mode, reverted to original app version by uninstalling, all to no effect. 😞
