It's amazing how bad Slack got. Android app looks slick and the UX is awesome, but functional bugs make up for it: last week I had all _my_ messages disappear from a conversation, I could only see what the other person wrote. I routinely have to force-close and reopen the app to have it show new messages. And for couple of months now, smileys typed in the app (e.g. `:)`) don't convert to actual emojis when sent. Support responded recently along the lines that "it should be fixed now because nobody complains anymore". Well it isn't, apparently sending a smiley to try and reproduce the issue is too much of an effort.
