Cant send message in mobile after uploading attachment

Just as the title says, found a bug where uploading an attachment in mobile on a PM disappears the send button.

I just checked, it doesn't disappear, but the attachment does put the send button out of viewport. A temporary workaround is flipping the screen. It's not ideal, but it works.

This will be handled in the upcoming 2.0 version though. Thanks for reporting.
