Looks like something not working as described on help for the "Force Sync" function.
I have 2 translation projects, then i select one file i have modified and i validate using "Force Sync".
Then nothing appening on destination file content, i just see the date change but nothing on content.
And some files stay as "Not translated" even after using the "Force Sync".
Anyone having the same issue on this ?
I don't think there are too many users of this new feature. You might want to try Support if no one answers.
See https://helpx.adobe.com/contact/enterprise-support.other.html#robohelp for your support contact options.
This has been enhanced in update 3 of 2020. Now in Force Sync you are presented with two options, whether to copy and update the timestamp or just update the timestamp. Do try out and let us know if you still face any issue.
