I appreciate the flexibility of the platform, the chat functionality, and the timelines built-into each task.

Dislike

1. Audiences - I find it a bit limiting that custom JS audience code may not work. When Optimizely audience code executes it doesn't wait for the full page to load. 2. Optimizely app is a bit slow, when navigating around the interface. 3. The code editor is quite basic. I have to write code in my IDE and copy and paste into optimizely every time I make a change.

The tool has soo much to offer but it requires a big learning curve as it is quite intimidating in sense of integrating it and learning everything about this tool.

Dislike

While the chat feature is helpful in maintaining consistent communication across teams, it can sometimes be difficult to find the correct threads within a workstream.
