I have now downloaded both the file available (right now) in the Support article and the most recent Android 10 download in Holoserica’s FP3 OS downloads topic, and both files have exactly the same size (to the byte). I guess Fairphone wouldn’t overwrite the previous upload with the newest one. So I would assume the Android 11 installation file is not uploaded yet.
@OldRoutard I have tried to clarify my original post above now.
