Hi,
I put my phone on silent mode. However, when I was using the lichess application, I did actually receive some noisy notifications with sound. Strangely, it only happens with Lichess and not with the other apps. On my second phone with Android OS, I never received any noisy notifications in silent mode from lichess, so I guess the problem does not come from the app
I triple checked to see if I deactivated the sound and I did. It did not happen before the last update. Do you also experience this kind of bug since the last update?
