Expected behavior
DC-Android and DC-iOS support markdown.
Actual behavior
DC-Android and DC-iOS do not support markdown.
Explanation
Text formatting, along with the use of emojis, is a great way to make parts of a message or the message itself stand out. Therefore, many messengers support it. For example WhatsApp, Telegram, Threema and Signal. Unfortunately, the situation in DC is inconsistent. DC-Desktop supports markdown, but unfortunately the other versions do not yet.
I use markdown, among other things, to format the text for self-created link previews.
