Please let us save our XD file on an oldest version.
Explaining my case:
I had my prototype that was working properly. You guys made the update, now I can´t work.
I noticed sometime later that my issue was the update.
I tried to revert Adobe XD to the latest stable version.
I cannot open my file there anymore because I saved it on an updated version.
Now I have 2 options: Wait you guys to fix my issue.
Redo my 7months prototype in another tool.
I wish I have a third option:
Save my XD file in an older version and come back to work.
