Biblatex APA6 not getting parentheses in year of in-text citation

I’m using Biblatex package and when citing in-text, i.e. cite{...} and it renders the year following author’s last name without the parentheses in the year, e.g. cite{einstein} renders as "Einstein 1905". And as long as I know, APA 6th edition rules in-text citations with parentheses, i.e. it should be "Einstein (1905)".

I’d be thankful if you could guide me in what is missing in the apa6 setup in Biblatex, and even if this mentioned package is reliable in terms of citing with APA for a journal article.

Thanks!

I attach my main.tex and sample.bib files and output:

documentclass{article}
usepackage[utf8]{inputenc}
usepackage[english]{babel}

% Sets-up bibtex for APA 6th
usepackage[backend=biber, style=apa,]{biblatex}
addbibresource{sample.bib} % Imports bibliography file
