Portfolio showing error in mobile view (chrome) on cellphone

Hi,

i bought the minicorp theme a while ago. everythings works fine except for the portfolio.

When looking on my mobile chrome browser on an iphone 5s (ios 8) the embedded portfolio films wont show up. instead there come the red field, which says: “sorry, there’s nothing to display in here” Link: https://de.vjsual.com/

in safari it looks good. also in other browsers on my computer. AND to make it even more interesting ;) the portfolio page with the same videos looks good as well in chrome on the iphone Link: https://de.vjsual.com/erklaervideo-erklaerfilm-referenzen/

any ideas to fix that.

Thanks Thorsten
