Highlights not updating on cloud

I use the Adobe Acrobat Reader app on my tablet to read and make notes on PDFs, which are saved to Adobe Acrobat Cloud / Adobe PDF services. Any notes and highlights I made on my tablet used to save to the cloud so that when I log into it on my computer, I can download them on my computer with all my notes but it is no longer doing that. Any ideas as to how to get that back?

Thanks!
