Unfortunately there is no available fix at the current time, not from Parrot, nor the underground market.
we are totally stuck with what we have. Unfortunately in your case you will have no choice to go to 1.6.7.
If you do that, see if you can get away without having to upgrade the firmware on your battery, as thats what seems to be causing the major issue at the moment.
Even the underground boys are not touching the Anafi, because the O.S belongs to them, will be copyrighted to them, and therefore any hacking of that system, would leave yourself wide open. Unlike DJI who used Open Source software belonging to the community, then ATTEMPTED to lock it down and claim it there own...... Which is why there was little they could legally when the team bust the mavic pro wide open.
If you want to continue flying at the present time, unfortunately you have to move forward.
