_I've already contacted PIA support team and they're working on a fix._
Non-the-less, here some code, that could easily check for the issue and fix it, if it occurs:
function pia-after-fix {
if [ -L /etc/resolv.conf ]
then
echo "It does not need fixing."
else
sudo ln -sf /run/resolvconf/resolv.conf /etc/resolv.conf
fi
}
