No puedo ver el pdf que abro

@adnirolc_7907 hmmm when was the last time you updated this app? Make sure you have the latest version of Acrobat Reader installed from your device's app store (Google Play Store or Apple App Store). Adobe frequently releases updates that fix bugs and improve performance. 

In every application, you have 'Cache' and 'Storage'—over time, the app's cache can become corrupted or overloaded, causing display issues. Go to your phone's settings, find the Adobe Acrobat Reader app, and clear its cache. This is different from clearing the app's 'storage' data, so you won't lose your saved documents. 

As a test, if you're viewing the PDF from a cloud service like Adobe Cloud, Dropbox or Google Drive, try downloading the file to your device's local storage and then opening it. Sometimes, network connectivity or how the app streams the file can cause the blank page issue. 

Worse case scenario, uninstall and then reinstalling the app can fix deeper issues with a corrupt installation. This is a last resort, as you will need to re-download any files you haven't saved to a cloud service!
