Sender address not provided

Hi everyone,

The other day I received some unexpected ETN on my online wallet. I wanted to check who sent this, to thank him, but then I realized that the sender address wasn’t provided, at all, as well on the app as on the web interface.

Why that ?
Wouldn’t it be relevant to know who sent you some ETN ?

Below the screenshot of the details provided by the web interface.

Thank you in advance for your answer.
