I am using the Shared folder to have access to files from two accounts. The problem is that when saving a file on one account I cannot edit and save it from another. It says I don't have permission to do so.
Both user accounts use a different Apple ID, but that shouldn't matter?
MacBook Air 13″, macOS 10.15
The basic POSIX permissions cannot provide what you need, so you'll need to add an Access Control List to allow that type of file server behavior.
I would create a subfolder to Shared and apply the ACL to that folder, but you could do it on Shared.
chmod +a group:<groupname> allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit /Users/Shared/<foldername>
You can just use staff as the <groupname> as your two users on that Mac are both part of staff. Or, you can create a new Group in Users & Groups System Preferences. Add each user to that group and use that instead of staff.
Replace <foldername> with the desired folder name, or delete it to just use Shared.

I should have put double quotes around the ACE, like this:
chmod +a "group:<groupname> allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" /Users/Shared/<foldername>
Here's how to share folders and change permissions to edit files

I suppose you are using iCloud Drive?
If you are talking about dropbox:

I thought I dont have to change anything, as it is the Shared Folder. I changed the permissions of the folder and hope it works now. Neither one of the user accounts was in the permissions so I put them in and set it to "Read and Write"
Thank you. I havent tried it because I'm nor sure what you are talking about. For now I changed the permission setting of the shared folder and set both user accounts to "Read and Write". I thought that what the setting was as it is a shared folder, but it wasnt set up like that. Lets see if it works.
