When replying to a comment in the Android app it seems to double post the comment. Sharing a story with a comment does not seem to have this behaviour, I only noticed it when replying to a comment on a shared story.
Device: Nexus 5X App Version: V4.6.0b3 OS: Android 6.0
Looking at the shared item after it seems like this must be a display issues as it seems the reply is only saved once.
Thanks Bryn, I’ve logged a ticket so that this will get fixed soon: https://github.com/samuelclay/NewsBlur/issues/828
