Can I really edit my Telegram messages only with the desktop client? I use Telegram both on my desktop and my mobile phone. On the desktop, I can edit messages I've sent, but on the mobile Telegram client I can't find this option anywhere. Does it really not exist or am I missing something. Or - should I look for an unofficial client for this feature?

Note: 


If I tap a message in a Telegram conversation view, the 'Message' context menu only has "Reply|Copy|Forward|Delete" - and no "Edit".
My client version is 4.9.1 (1361) arm-v7a
A simple tap on a message you sent recently will bring up the action menu containing "Edit".
