In the following post a user indicated that they reset their InDesign preferences and the issue resolved itself. Have you tried that?InDesign CC 2015 Overlay Panel Acting Buggy?

We don't know exactly what will happen but are in the process of auditing all the calls we make (they all appear to be HTTPS), as well as working through testing with the beta. We will have more details once we have completed our testing.Also, as with past iOS betas, if you have access to them we suggest you take some time to evaluate your own apps on them.

I'm working in Windows, on a bit of a slower machine. The thing you mentioned does sound like the issue, except mine don't go away in a second or two. Sometimes it takes up to 10 minutes or more to go away, if at all. There are no particular steps to trigger it happening, it just happens or it doesn't. It only became an issue with the new overlays panel, before that everything worked fine.

Hi Leo -I moved our content off our server and we have had no issues with losing content on the app/iPad. Over a couple weeks and clues working with an Adobe Engineer, I put some pieces together that allowed me to figure out it was an uploading issue through our network.

Any update to whats going on with this? I'm still having the same problem in CC2017. Constantly having to rename the App Data files is getting old.

Leo, the other thread is focussed on iOS. Your behavior is very odd. I think you should open a case with our support team so that your project and account details are captured and can be tracked.

Great. Thanks for the time Nathan. As for timing I also took time to try in preview app, clicking refresh or preview update. I also have testing in non-preview app and made sure to publish and wait. And results are the same.thanks again for your support.

Looking into this further it appears uploading a smaller image for article image and social image don't change the content file size which in my case is red and to big. But it sounds like that may or may not be whats causing the jitter on the page that is in the browser, and the app content pages with the cards and card images may be causing the Jitter or its a combination of both.Nathan sounds like adobe is streamlining the image thumbs that we upload fro each card. Great.So we will focus on re...
