This feature used to work in previous releases. I’m not exactly which version is stopped working in.
As you attempt to clone a step from one project to another, if you click into the “Select Project” combo-box and then start to type, no selection is ever matched to a project. You have to manually scroll through the project list and click the one you are looking for.
Thanks for getting in touch, I was able to replicate this on my local instances - looks like that drop-down functionality was changed in 2019.10. I’ll reach out to the team and see if I can get some more details on this, and get back to you as soon as I hear anything.
