Hi Nackapan I've sent a message to the Health Unlocked team about this so will report back once I hear anything. I found this function under Menu > Get Help Using This Site > Ask. You can see the 'Ask' button at the top of the box that opens up, then you can leave your contact details and message. This is how it looks on my laptop, not sure if it's the same on phones. I have contacted HU this way before and they were super helpful.
