Ah, I misunderstood, so I retract my previous statement.
YES, P0 could very likely be your issue, and if its not now, it certainly could be in the near future.
P0 is definitely not a reccomended location for a flex implant.
My reccomendation, but your decision
remove it carefully, test that it is still working, then reinstall in another location
P1 would be a good option for you.
