I'm using the latest version of XD on a Windows 10 machine, and it constantly crashes. Often without warning, and without doing anything (i.e. it is standing idle). It's getting very frustrating as it happens 3/4 times a day, meaning I often loose work and can't make much progress without the worry that is going to crash!
On another note, is there anything on the roadmap relating to opening and editing Figma files in XD? Meaning I could work in Figma, and then back up the files in XD for the rest of the team to access?
That's definitely unusual. Can you turn on crash logs (link below) and send us a .link to the dmp file of when it crashes?
Also, there isn't anything in the short term roadmap for editing in Figma. You can upvote here: Import or export Figma (.fig) file – Adobe XD Feedback : Feature Requests & Bugs
