Individuality depends on the existence of the ego. Does ego remain after mukti? The answer is that it depends on the spiritual aspirant.
AMRITA: "Sir, how do you feel in samadhi?"
MASTER: "You may have heard that the cockroach, by intently meditating
on the brahmara, is transformed into a brahmara. Do you know how I
feel then? I feel like a fish released from a pot into the water of
AMRITA: "Don't you feel at that time even a trace of ego?"
MASTER: "Yes, generally a little of it remains. However hard you may
rub a grain of gold against a grindstone, still a bit of it always
remains. Or again, take the case of a big fire; the ego is like one of
its sparks. In samadhi I lose outer consciousness completely; but God
generally keeps a little trace of ego in me for the enjoyment of
divine communion. Enjoyment is possible only when 'I' and 'you'
"Again, sometimes God effaces even that trace of 'I'. Then one
experiences jada samadhi or nirvikalpa samadhi. That experience cannot
be described. A salt doll went to measure the depth of the ocean, but
before it had gone far into the water it melted away. It became
entirely one with the water of the ocean. Then who was to come back
and tell the ocean's depth?"

It is possible to choose one's own state.Those who choose to remain at the level of the Absolute do not have individuality. Those who prefer to stay in the relative plane retain individuality.
MASTER (to the devotees): "Ordinary people do not recognize the advent
of an Incarnation of God. He comes in secret. Only a few of His
intimate disciples can recognize Him. That Rama was both Brahman
Absolute and a perfect Incarnation of God in human form was known only
to twelve rishis. The other sages said to Him, 'Rama, we know You only
as Dasaratha's son.'
"Can everyone comprehend Brahman, the Indivisible
Existence-Knowledge-Bliss Absolute? He alone has attained perfect love
of God who, having reached the Absolute, keeps himself in the realm of
the Relative in order to enjoy the divine lila. A man can describe the
ways and activities of the Queen (Queen Victoria.) if he has
previously visited her in England. Only then will his description of
the Queen be correct. Sages like Bharadvaja adored Rama and said: 'O
Rama, You are nothing but the Indivisible Satchidananda. You have
appeared before us as a human being, but You look like a man because
You have shrouded Yourself with Your own maya.' These rishis were
great devotees of Rama and had supreme love for God."

People who follow Bhakti Yoga prefer to remain in the relative plane and so retain their individuality. People who follow Jnana Yoga prefer the Absolute and give up their individuality.
There is thus no contradiction between the Vaishnavas and the Advaitists. They are talking of two different things.
