I have been searching for this option extensively. I am using mobile browser to check dji forum. One of the admins or dji representative messaged me regarding me drone s/n check. I don't see any notification, no menu to check, no email, nothing. So where does a pm message go?

Hi nikagrawal, sorry for the inconvenience, kindly please check the Personal Message when using computer browser, the mobile doesn't has this function as present, thanks for your kind understanding.
