I run a 100% Linux household for my personal devices. However, work does not allow the use of Linux devices, which is why I have this question. I am permitted to use WSL.
Although I use Molly myself and it's quite great, I never had issues with Signal's notifications on GrapheneOS, LineageOS, or CalyxOS.. Definitely stick with Molly, if you can!
not entirely since I work from home 🤣
