I think of myself a pretty advanced user of RoboHelp (over 20 years). We recently upgraded projects from RoboHelp 2017 to RoboHelp 2020. The upgraded was valided sucessfully.
I have added the upgraded projects to SharePoint Online and can see the projects through the RoboHelp Collaborate connection profile.
However, I have struggled to download a project from SharePoint online for myself or any of my technical writers. The Adobe documentation provides a simple three-step instructions that simply is not working for us.
