Currently using 0.5.22.8 Beta on MacOS.
If I check for an update, it says I have the latest. But when I go to Share Online it says this version no longer allows you to share designs. And that I need to update to use this feature. But... I can't. Opening CC and being logged in, I see no way to update to the latest beta version.
Any ideas... ?
You're using our late September release. You should update to our most recent release (November) to ensure you can share. The current build number is 0.6.2.7. One thing you can try is to uninstall the current version using the Creative Cloud and then installing again.
Hope that helps!
