I'm having this issue
I have some custom fields imported from a managed package which I need to set to "Read only".
I have set the FLS to read only on these fields for all users but when I navigate to the page the edit option is granted and modifications are changed! I even set it to read only in the page layout but it still editable
Do anybody have an explication or can help please?

    This is likely the "Edit Read Only Fields" setting in your permissions for your user. See this Q&A and this knowledge article.

  • This was helpful. I ran into a similar issue where all the Profiles were respecting the FLS setting except one Profile. This was the solution to that. Thanks @A.Amel Commented Jun 21 at 16:02

Finally the user I've been login with had the 'Edit Read-Only Fields' permission via his profile, so he could edit no matter what, I only had to uncheck the permission. Thank you ! Edit Read-Only Fields permission
