CAN'T MENTION, TAG, AND PUT EMOJIS WHEN BREAKING THE LINE USING ENTER ON MOBILE

While I'm announcing, I can't tag a channel when I'm making another line on my message (or just tap enter on keyboard) but when I clear the line I created, it highlights, but I need to make a line, so I did is to copy the ID of a specific channel I want to mention, which is hasle but I have no chance for it, it doesn't happen on previous versions but I'm on beta, I hope you will fix it on the next update. 🙏🏼
