SOLVED FTP read only access problems

[Artichoke]

I have a small TrueNAS server set up and I can access my files over SMB. I want to access it through the internet to I want to access it via FTP as well. FTP successfully connects but I cannot read/write to any of the files. I am guessing that I have something wrong with the permissions my users and groups?
I can give any details required but there are so many I could give but I don't know which ones so please let me know what details to post here.
Things I have done already:

• Tested on Mac, Win10 and Ubuntu 20.04
• Added FTP group to the user
• Set all folders to Read Write Execute in FTP settings
• Tried setting Read Write Execute to all of the users home folder
• Create a group called ftpuser and add it to the desired user

permissions
edit: I should also note that when i say read/write, I can still see the files but I cannot open them and edit them. e.g. I can see an image file, but I cannot open it. on a Mac it just says "Preview was unable to open this file."

repost from StackExchange here due to lack of attention.

Does anybody have any ideas? I have been stuck on this for a while now and I'm stumped for a solution.

Perhaps allowing execute might help.

I finally found the problem after all this time...
In my initial post I said that I tested FTP access on Ubuntu and windows. I don't know why I said that because I just checked today and they both work fine with FTP access. MacOS however, still continues to only do read-only and I found out why: MacOS no longer allows any sort of FTP read and write access through finder. The solution is to use software like Transmit or Cyberduck.
