When sharing a media from WhatsApp to Telegram, sometimes the media is not shared, and only a message with this appears :
- - - - Sent from WhatsApp

In one of the latest versions, WhatsApp changed its way of sharing contents. In the previous versions, it was shared as "media type" but now it is shared by default as "email type" so Telegram can't grab informations about Medias shared in this way.

In order to share medias from Whatsapp, the user has to use the old "media method". In order to do this, the media has to be shared once opened (as it happens in Telegram) and not directly from the chat list.

In this case the media will be shared without problems.
