Hi Istvan,
If you have customized GeneratePress’ core stylesheet, then yes, your edits will be lost on update. This is because when you update, all GeneratePress files are deleted and re-uploaded.
That’s why you should always use a custom CSS plugin (https://wordpress.org/plugins/simple-css/) or a child theme to add CSS edits to the theme.
Let me know if you have any more questions 🙂
Tom
