poubellier Do i necessarily have to install it from the play store on the owner profile and then install it to the sandbox profile through GrapheneOS's settings for it to work?
No, that wouldn't make a difference I'd expect.
poubellier So what could be the problem now?
Can't know for sure. I found the logs you shared on Matrix and it appears the issue you're experiencing is different. You said you installed it via Aurora. Did you install it using the session installer (if you are/were using an older version of Aurora)? If not, you can try reinstalling.
