Bridging Markdown from Telegram to Whatsapp doesn't work

[timbimbim]

Hi!

I forward all my articles from a blog to Telegram via a wordpress-Plugin, that uses MarkdownV2 ("WP-Telegram")

Then i use matterbridge to forward Text and Links from Telegram-Channel to whatsapp-broadcast-list.

In Telegram the message still looks great (Title ist bold, excerpt is normal, and than link-preview is shown.)

Unfortunatly in Whatsapp it ends looking really bad: No more bold, no more paragraphs, no more link preview.
See here: (left Telegram, right whatsapp after matterbridge)

Some body has an Idea how to change that?

Ps. this is my matterbridge.toml.

[telegram.mytelegram]
Token="XXXX"
RemoteNickFormat="({PROTOCOL}) <{NICK}> "
MessageFormat="MarkdownV2"
[whatsapp.mywhatsapp]
Number="XX"
SessionFile="session-XX.gob"
QrOnWhiteTerminal=false
RemoteNickFormat=""
[[gateway]]
name="gateway 1"
enable=true
[[gateway.inout]]
account="whatsapp.mywhatsapp"
channel="111@broadcast"
[[gateway.inout]]
account="telegram.mytelegram"
channel="-XXX"``
