I'm writing in hope anyone can support. I'm using the Pixel 7a with the latest update of GrapheneOS. One day I enabled the "Do not Disturb" mode - it worked fine, but after deactivating this mode, nothing happened. There are no sound notifications anymore. I first thought there is something wrong with the hardware, but playing music is working well. Also changing sound notifications to any app does not change the result. The phone is just vibrating. Restart and force close apps does not change anything.
Is there anything I can try?
