won't work on IOS

I’m getting some weird behavior when using, I am using it in 3 places, the first place is before you sign in as it opens a signup page in your browser, the next two places are after you sign and are used for invoicing/statements and should open a pdf in the browser, however these 2 do not open for some reason. I am unable to check the logs(lack of a mac right now), works perfectly fine on devapp, so this might be hard to diagnose but any ideas would help. This is what I have for CSP

I was thinking it might be (Apple Transport Security) but im using https links for creating said pdfs on the back end so i’m not really sure.
