You might not have installed DoozyUI the proper way.
To start using DoozyUI you need to do the following steps:
1. Import DOTween from the Asset Store
2. Do its initial Setup (this will add some missing files that are required for DOTween to work properly)
3. Import DoozyUI
This is the proper way of starting to use DoozyUI as it takes advantage of the efficient tweens that DOTween provides.
If you're not sure on how to do it, just watch the 'Initial Setup' video (2 minutes) at https://www.youtube.com/watch?v=8Cnl6bub8n0
Also, we recommend that you look (or at least skim) through the manual so that you have an idea on how the system works and, should you want to learn even more, you can watch the video tutorials that are available on our YouTube channel.
