Composed message goes to Drafts folder instead of being sent and saved in Sent folder.

Context

I keep Dekko2 on all the time on my UBports Meizu Pro 5. I did that by going to UT Tweak Tool and prevent app from suspension. Sometimes, when I compose a new message (or reply to an existing one) and hit Send I watch the popup that says "Message queued" but then the second message with "Message sent" doesn't come up. I find the message then in the drafts folder and not in the Outbox or Sent folder. In order to send the message I have to close Dekko, reopen, go to Drafts folder, click on the message to open it and send it again. Now it is sent and saved into the Sent folder.

Expected Behavior

It should alwasys send the message.

Actual Behavior

Sometimes it doesn't send the message but saves it into the Drafts folder instead while it only displays "Message queued" but not "Message sent".

Steps to Reproduce

1. Prevent Dekko2 from suspending
2. Write a new message
3. Press send
4. Sometimes it doesn't send it.
