Files are lost from the previous version in XD

I'm a UI/UX Designere. Adobe XD is a PAID product and you have yet to deliver basic features. Especially the cloud problem.

It's not like you've never developed similar software before,

you've been doing it for years you know the drill. 

It's been an error for several days.

In the previous version, the cloud and library stopped working, so I couldn't collaborate in XD.

so, I re-installed a new version, but it's in the same state.

and now, some of the important files from the previous version disappeared in the cloud.

I'm Korean, and the Korea Customer Center is not solving anything. It takes a few days to ask your headquarters and solve it. I'm about to release an app. What are you going to do with my lost file?

What should I do? f*** adobe xd developers
