    I cannot regress my project version far enough without it breaking other assets. This needs to be fixed immediately, this is the main file format for assets.

    Still in effect. Every new FBX's import tabs just floods the console with errors and animation information cannot be accessed. Test your builds before you release them, please.

    When comes this great day, when Unity before publish their new releases will start testing own program? I am tired every time rolling back projects to older version.

    2019.3.0f6 here, same issue when trying to import .blend files directly (since internally it uses the .fbx importer anyway). Only feasible workaround that doesn't require a previous Unity install is to export multiple .fbx files (or in my case .blend files) each with one and only one animation, as mentioned in a previous comment.

    Same issue. Making it very hard to progress! Opening in another version of Unity doesn't seem to help.
