In this SE post, there is code from lockstep showing how to put in BibLatex citations in footnotes in Beamer pages with columns.
It seems to work well if there is only one citation in one Beamer Page.
However, there seems to be two problems:
(1) when there are multiple citaitons in one page. The numbers in the footnotes are wrong (the numbers outside the footnotes are fine), as shown in frame 2 and 3 in the compiled Beamer PDF. Specifically, the entries in the footnotes have a same preceding number. Could you help to comment how to solve this problem ?
(2) when the same citation is cited across different Beamer pages, the citation number is incremented. Is it possible to use the same number for the single citation ?
Many thanks !
