I have a Google Pixel 7 with GrapheneOS installed and Sandboxed Google Play running. For the past few days, some of my notifications have been delayed, sometimes by around 30 minutes. Some of my notifications appear on time, however. To be specific, notifications from Messages, Discord, and Slack are sometimes delayed. I'm not sure if it matters, but I use a VPN that is set to always be on. I am using the stable release channel, and my phone is up to date. Any help is appreciated, thanks.
