Its pretty clumsy that File Embed renames PDF uploads. So for example a file called “File_Embed_Manual.pdf” is automatically renamed in something like "
6ba8b0b6-1010-4647-82ac-3fb63f8eb329.pdf". Clients who download such weird names can never find it back on their computer. Hope this can be fixed in a future version.
