Hello all! Another status update on this. We believe we’ve resolved the issue with being unable to load previously saved files in 2.3. We hope to ship this fix next week, but if you need immediate access you can join the Dimension Prerelease Program using this link:
Once you’re on the Prerelease website, simply download the Dimension build marked “2.3.1 – r.1054” which contains the fix. It should open any files that weren’t working before.Caroline Mitic commented
Wow, this just happened to me too. Downloaded the app yesterday, saved a file today and now I can't open it. UGH.
