Adobe XD is the first all-in-one cross-platform tool for designing and prototyping websites and mobile apps.
Adobe XD provides 3 UI kits built-in. Windows, Google Material design, and iOS kits.If you are trying to open any of these UI kits but a blank project opens then all you have to do is wait for few minutes.
It takes 5 to 10 minutes for the UI kit to open for the first time. I banged my head for 5 minutes trying to open material UI kit
Happy prototyping 😀
