Falha do Aplicativo: fechando sozinho

@fernando_1475 sorry to hear this sudden crashing! I would clear the cache, history and cookies. If the issue still persists, it might also help to clear the app's data (though be aware this might remove any locally stored settings within the app, so you might need to sign in again). To do this, select "Clear data" instead of "Clear cache." Another potential workaround to improve stability is to ensure you don't have too many other memory-intensive apps running in the background simultaneously, as this could be causing the system to terminate Adobe Acrobat to free up resources. Closing unnecessary background apps before working in Adobe Acrobat might help prevent these unexpected closures.
