Steps to reproduce

1. I was in https://matrix.to/#/%23element-x-ios:matrix.org
2. Typed a msg (using normal composer; nothing special)
3. Hit send
4. No local echo
5. No remote echo
6. Checked in another client; the msg never sent.
7. Msg not shown as failed.

Looks like something went wrong in the SDK:
