I have Graphene running on my Pixel 8 and everything works like a charm. Pretty sure the following is some mistake of mine since I could not find anything online but I can not figure this out.
A few days ago I tried to use the Finamp app with my Jellyfin server but all requests resulted in an invalid certificate error. I first thought that might be a problem with the app since Vanadium and Firefox can access pages on the server without problem and show a valid certificate. Also there were some issues on their github about troubles with Let's Encrypt. So I thought that might get fixed in the next version.
Now today I tried another app which exhibits the same error so I checked the installed certificates. But I can not find Let's Encrypt under the system certificates. What am I missing?
