I have a Zagg Keyboard. For a while it worked fine when I used messenger. I thing the problem came alone when I up dated software. The issues is before the update the enter key moved the cursor down a line. Now the enter key send message. I can't stand this and want it back like it was before. Any ideas???
This behaviour is up to the app/website to decide, so unfortunately you cannot change it back yourself. However, pressing Ctrl+Enter is a common shortcut on Mac and iOS to insert a linebreak when Enter normally submits.
