The latest update to Adobe Muse CC, 2017.0.3, is now live. You can download the latest version from your Creative Cloud desktop app. Because it takes around 24 hours for the list of apps to get automatically refreshed, log out and sign into your CC desktop app if you don't see the latest version listed.
This release contains performance and stability improvements, and fixes for the following user-reported issues:
Attempting to re-publish a .muse file results in the error message: server may be missing or incorrect.
[Mac] Blank composition triggers are not clickable when set to Lightbox with a mouse rollover event.
[Chrome] Featured news composition does not close the target box after rollout operation.
When a page is exported and previewed, the composition widget container disappears on mouse rollover.
Video widgets poster image gets re-rendered while switching between breakpoints.
Changing the filename of a page excluded from Menu links causes the Muse app to quit unexpectedly.
Using horizontal and vertical Menu across pages containing multiple breakpoints causes the app to quit unexpectedly.
The Muse app quits unexpectedly when the Preview button is clicked.
