User @Alipio recently spotted this bug Going to try and quote his words: "When a message with this format is sent: <a href='po:send//commands'>commands</a> crashes the PO Android app of any user that receives this message, this represents the HTML message represents the link to send messages, similar to the ones used in Safari back when the /catch was a clickable command." Also said that basically any message that has HTML features (sys.sendHtmlAll(Msj,Canal) (Canal = Channel ; Msj = Msg or Message) basically crashes the app of anyone that sees it. Hope this is explicit enough. He might elaborate more into it if it's not clear enough. But for now he's sort of busy so he asked me to report in his place.
