there is still a free version of adobe xd? i have problems to download it

Hello @Fernando32067847vsww, I think @Rishabh_Tiwari's answer here clarifies the situation:

"

Hi @Leslie2628726265vb ,

Adobe XD is no longer available for purchase as a single application but will continue to be supported for existing users. XD will continue to be available as part of our Adobe Creative Cloud All Apps subscription. We will continue to support existing Adobe XD customers.

Thanks

My personal opinion and suggestion is to switching to Figma or if you're going to start learning/using a UI/UX specific design tool, starting with it, since looks like the acquisition of Figma by Adobe is going to be completed later, and it's going to be the tool that's the most common, if you haven't used you can start using for free, here's a "baby step" kind of 5 min tutorial to get started: https://www.youtube.com/watch?v=7TF2ZmtkZz0 
Hope this helps.
