Transcendence of values of Fredholm series at algebrtaicalgebraic arguments

Let $d$ be an integer greater than $1$ and let $f(z)=\sum_{n\ge0}z^{d^n}$ be the Fredholm series. It is well-knowmknown that the Roth-Ridout theorem implyimplies that $f(r)$ is a transcendental number for all non zero-zero rational $r$. By MahlerMahler’s method, it is even true for any nonzero algebraic $r$. Can one extend the arguments of the proof based on the Roth-Ridout theorem to recover Mahler's result?

ThanksThank you in advance.
