I can only see nintex workflow(imported) which is attached to a list, not visible to others who are all site collection administrators, When they try to access the workflow, it says "Error: cannot find workflow in repository". I am the one who imported the workflow and attached to a list, i can see the workflow and can modify it but not others. Any suggestions would be highly appreciated.
I am able to find an issue, if you go to http://sitecollection/site/NintexWorkflows/Forms/AllItems.aspx
There will be a folder with your workflow name, click on the folder, inside again you will find three files which are checked out to me. I have checked in, then everyone is able to see the workflow. Thank you.
