My app is no longer working

Hi there

Hope you are doing well and thanks for reaching out.

What happens when you try to use the app? Do you get an error message? If yes, please share a screenshot for more clarity.

Also, share the version of the OS and the Acrobat App you are using. Tap on Profile> About Acrobat and check for any pending/missing updates from the App Store (iOS) or Play Store (Android). Reboot the device once and check if that works https://helpx.adobe.com/acrobat/mobile-app-faq.html
