PDF not saving highlights

[will_9836]

I am using Acrobat web browser version, as I do not currently have access to the app. I'm working on a pdf I have saved to the cloud, and I closed the document, and opened it back up shortly after, and the last 45 minutes of highlighting had not been saved. The bit I did before that did though. I highlighted it again, and checked, and again it did not save.

@will_9836 never rely on the autosave. Always manually save it. Periodically by clicking the "Save" icon or using the keyboard shortcut (for the PC, Control S or for the MAC, Command S). Also, ensure your internet connection is stable, as connectivity issues can disrupt the autosave process. If the problem persists, try clearing your browser's cache and cookies or using a different browser to see if that resolves the issue.
