Since the latest alpha I don't receive notifications in whatsapp if I use contact scopes with selected contacts. If I select normal contact mode it works as supposed.

I also can confirm 2024110700 fixed this.

I think I will disable autoupdates and install them manually with 1 month delay. Security is not that important for me. I like GrapheneOS most because it is pure Android with some very clever imporvements (e.g. USB-C, Storage/Contact Scopes, Privacy by default, Sandboxed Google Play, ...).
Updating two times a week and "unstable" releases with bugs like these are a PitA for me.
