What should I do? The mobile Safari browser, and other mobile browsers, do not always display PDF certificates because of the fillable fields in the PDF. If you are using an iPhone or iPad: 1. Download the Adobe Reader app. 2. Open the certificate again. 3. When the certificate opens, click on **Open In...**. 4. Select Adobe Reader. This will allow your certificate to display correctly on your mobile device. ## ## Related - [SmarterU Mobile](/smarteru-mobile.md) - [Supported Browsers, Operating Systems, and Screen Readers](/supported-browsers-operating-systems-and-screen-reader.md)
