I've had a few odd bugs with the new CC 2017 update, but none seem related to webassist extensions. I've had php code mysteriously removed from pages and I have a script file that uses &lt; and it is getting converted to < automatically when I open the page and that breaks the script. When I create pages or save as the site tree doesn't update to reflect the new page and there is no refresh button, just a sync button.
I'll keep using it, but I hope there is an update soon. This seems half baked still.
Did this help? Tips are appreciated...
