Completely unreliable Notifications arrive in bulk even if I have seen them before If a message fails to send because of no internet, it never succeeds to send again even if the app is in the foreground Not all messages are shown even if I am connected, I have to close the app multiple times and open it again to finally see the messages If really try not to use it Please fix! I happy to provide more info if needed

Android app is quite buggy. All direct messages have 'Couldn't send, tap to try again' error with a white picture above it. This is for pictures send from desktop. While these have been transferred just fine. Very annoying since you have to constantly scroll up to see the last direct message text. Please fix this. This has been an issue for over 1 year.

I really love Slack, but the new UI that was introduced a few weeks ago makes it unusable. A lot of the time a whole string of messages are hidden from a conversation that I do see on my computer. These gaps in time make it very hard to have good communication. Also the search functionality, e.g. searching for messages `from:@user` don't always show all or any results. These problems have persisted for weeks and no option to go back to the old UI. Please fix it, Slack!
