mythodical It sounds like you might be using apps that have not been updated in quite a while. You might want to consider alternatives.
These are apps that have had updates released in the last week, so I'm not sure how you came to that conclusion.
I would really just like to know if this is a misconfiguration problem on my end or if this is just how GrapheneOS works. If it's the latter, maybe GrapheneOS just isn't the phone OS for me. I have enough daily tasks I have to do in my life and I don't really want manual daily app updates on my phone to be yet another one of them.
