More confusing one is that flatpaks can't access mount points inside your home directory even with the correct flatpak permissions set. Assume that you are running Steam as a flatpak and you want to add an extra drive to store your Steam library on and you have your extra drive already automounted inside your home directory and the correct flatpak permissions set, Steam will not find it anyway. You have to use a mount point outside of your home directory to get that to work.
