Réparation

Merci beaucoup je vais essayer 

@eveline_1667 the suggestion to repair the installation is a bit confusing since it's a mobile app and doesn't have a traditional desktop-style installation that you can repair. On mobile, the typical way to address issues with an app is to first ensure it's updated to the latest version by checking the Google Play Store or the Apple App Store. If it's already up-to-date, the next step would be to try clearing the app's cache and data. You can usually do this by going into your device's Settings, then finding "Apps" or "Applications," locating "Adobe Acrobat Reader," and then selecting "Storage." Here, you should see options to "Clear cache" and "Clear data." Clearing the data will reset the app to its default state, so you'll likely need to sign back in.

If the download issues continue after trying these steps, the next best workaround would be to uninstall Acrobat Reader Mobile app and go back to Google Play Store or the Apple App Store, and make sure you download the correct Adobe version, not some look-alike app! https://www.adobe.com/ca/acrobat/mobile/acrobat-reader.html
