I always post my message to the Outbox before syncing.
Recently if I wanted to edit my message before sending I find 2 messages have been sent ie the original and the edited one. Also the outbox is very sensitive and can send a message sometimes without syncing. My time delay for messages is 30 mins.
This never use to happen and you could open your message from the Outbox /edit it/sync
Any ideas out there
