I'd like to know about this as well. I'm getting the "canna access google lens" type error when I try to use the google translate app. I'm able to download offline languages when I allow network permission. Then I disallow after I downloaded. But nothing I do is getting the camera option to work. I even realized theres a google lens "app" ( I thought lens meant the physical camera) and went and downloaded that. Still doesn't work.
I need an app for real time (camera) offline translations with my phone. Pixel 7a.
