Zoho User can't access associated Project Documents

Zoho User can't access associated Project Documents

We have a new bug/issue with Zoho Projects. My staff could first see documents when a task was created in a project, then it stopped working. I have to manually share each document with them to see.

We have a integration from Zoho Forms, where a brief will be created as a task in projects, and the documents load. I (as manager) will then associate the staff as the task owner, and they still can't see the files.

Can't see in setting where this may be causing an issue?
