@Elleaster @noodlemaz +1 to Moshidon.
Don't think it will protect against the phone auto-killing the app (which is what's happening there), but you can click the X as if you wanted to cancel the post/reply and it asks if you want to save your changes.
You then go to your profile and click the folder icon to resume unsent messages. Then click the X where it says it "will save as unsent" to post.
I tested this 3 times during this reply.
