It is my whole profile as well, not just the ln address, showing months old data. A strange bug.

That is how they implemented it. Hope they will figure it out and sync data from user's relays, using on login trigger event.
Even stranger, this is only on my phone. I tried a totally clean browser profile on both my laptop and mobile. Laptop shows the correct info, mobile shows months old data. I don't understand what is happening 😂
