Not sure if this is the right place to post, so correct me if it isn't.
I've had a few issues with so far with GrapheneOS in the few days I have been using it. Such as the Night Light not turning off on schedule. And I could not turn the Colour correction off once it has been turned on, had to restart.
I've also had trouble setting Startpage as my default search engine in Vanadium.
Overall though I've really enjoyed using Graphene so far.

    khrom to get Startpage listed you must first open Startpages settings and change POST to GET. Then do a search.

    Open Vanadium settings then you will see Startpage listed.

    You can then revert the change back to POST.

    Regards night light I will test and come back to see if I can replicate.

      MetropleX just to confirm Night Light is broken, however restart wasn't necessary. While the color correction remains the toggle does move to the off position. Toggling back on, then off turns off color correction.
