Determine whether the following statement is true for every polynomial PP of degree at least 2 with nonnegative integer coefficients:

There exists a positive integer mm such that for infinitely many positive integers nn the number Pn(m)P^n(m) has more than nn distinct positive divisors.

Remark. Here PnP^n denotes PP applied nn times, this means Pn(x)=P(P(P(x)))n timesP^n(x) = \underbrace{P(P(\ldots P(x)\ldots))}_{n \text{ times}}.
