Citing author with different years in ONE quote

I'm failing on a condition for the in-text citation. It is "If multiple sources from different years are cited by one author, the author's name should be mentioned only once in the citation." Example "Maier 2018, p. 10; 2020, p. 30."
Also, my ibid rule does not work yet, i.e., multiple passages by one author from one work, but on different pages. Example "Müller 2017, p. 20" next quote "ibid, p. 40".
Can anyone help me? Many thanks in advance:)
