Problems with fonts on iPhone

HI i did integrate the font family Montserrat. It works fine, but not on iOS. The google fonts are correct. @norm Whats the problem?

With only a screen shot to work with, I literally have no idea.

I would need a little more info, a live link at the very least.

Now it works fine.When i delete the fonts folder manually and extract the project again, the fonts will be changed. it seems to be a little bug.
