PDF fehlerhaft angezeigt auf IPhone

Are you using Adobe Acrobat Reader on desktop as well as on mobile to open or work on pdf files?

I don't know what's the standart for opening PDF filed in smartphones.
It's a general problem for IPhone-users in our Readers.

Also, the pdf file that you are referring here, is that pdf file is created using Adobe's Acrobat application or any other pdf maker?

We use InDesign to create the PDF and the problem occurs with all PDF-versions you are able to choose.

It could or could not be issue with the font used to create the pdf file, which isn't displaying correctly when opening in mobile app.

The used font is Molengo. With for example Arial, the problem does not occur. Is there any possibility we can use the font of our choice without using a "standard"-one?

Please check with a different pdf file and see if that is also changing the fonts when you open it on mobile device.

Unfortunately, the problem occurs with every kind of PDF file.
