I notice two things:

1. No suckers.
2. Compared to your first photo, almost all of the old leaves have died.

My plant is like yours in those respects. But, I know that my older leaves are dying sooner than they should. Does anybody know the cause?

As an experiment, I am thinking about spraying my plant with 250 ppm silver nitrate because it is an ethylene antagonist and ethylene promotes leaf abscission. See

Also, I have a small fortune in silver nitrate gathering dust in my basement that I haven't used in 45 years. Who else but me hoards that kind of stuff? Ha, ha, ha, the advantages of being me.
