Has anyone tried using their Z5 underwater?

Hi all! I just wanted to ask if anyone here has already tried using their Z5 for underwater shots? I just wanted to know as underwater usage is going to be my deciding factor in buying the Z5P. I know they're IP-65 68 rated but Sony's policy for waterproofing has changed. So yeah, just curious if the Z5 still has Sony's much-touted waterproofing ability. Thanks!
