I have the following main document, which is normally a lot longer. In general, I have the title page in a separate document and include this via \include{titlepage}. How can I change the margins and BCOR for the title page only, so that the title sits in the centre of the page?
I tried titlepage=firstiscover,titlepage=true, and \begin{fullsizetitle} as recommended here which all did not work. I also tried to compile the title page separately and include the pdf, but this produces a clash with pgfplots.
Thanks for your support

centerenvironment might add unwanted space. If you're in an environment already, it is advised to use\centeringinstead. – Skillmon Jan 30 '20 at 12:13
