iFrame hyperlink doesn’t work

I’ve been using Auto iFrame for a few weeks but I just recently noticed that the hyperlinks to the embedded post do not work when you click on them. They only seem to work when you right-click and ‘open in a new tab’. Is this a bug or a clashing CSS property? I like readers to be able to click/tap once to follow the hpyerlink. Thanks
