on my site I want special groups to see and be able to download different files. If somebody of the group that has no access right to the file, then he should not see the download link and in any case he (or her) should not be able to download the file.
Right now everybody is able to download the files but only registered users (as customers) who logged in shall be able to download.
I have created a group "customer" (in the screenshot below it says "Kunde" as it is a German site) who shall be able to download files (product data sheets of our products). I linked the "Download" to customer and also the layout to customer but still everybody (guest) can see the download button and download the file.
What am I doing wrong? Where is the difference between Categories and Access Rights?
I attached the relevant pages below.
Thanks for your help
