Double posting bug (multiple comments posted)

I'm using the Android Reddit app, but often in patchy coverage (commuting by train, through tunnels, under bridges, etc). Sometimes connectivity is patchy when posting a comment, and the result is two or three postings of the same comment, clearly as the app retries.

Sometimes the app announces a timeout, but the post was submitted, meaning a second attempt will result in a double post.

This is not the first time this has been reported, and after more than a year, I'm surprised this replay issue isn't already solved.

There seems to me to be a gap in the API that allows this situation in that there is no unique submission identifier to avoid replay.
