    Slack uploads pictures hellishly slow compared to messenger on mobile and generally sucks ur battery life. I am trying to get my group to find a better app so our phones don't die over the weekend. Full Review

    When a new message comes in a thread, it does not automatically appear. You have to go to another channel and then reload the thread to see the message. Please fix. It's really annoying. Thank you for the great work uptil now Full Review

    Solid app. Notifications can be a bit buggy and reading missed messages doesn't always work. Overall solid. Full Review

    Terrible design. Every group I join I have to make an entirely separate Slack account for. Sorry but you guys really screwed that up. You need to listen to your users. Thousands of us are calling out for single log in, like every other app has managed to offer. Full Review

    Good app but has some issues. High power usage warnings from android system. Good feedback in trying to get it fixed though. Cannot believe that people go to so much effort complaining about emojis but hey that's the world we live in now. Full Review

    Prior to the current update I would rate this app highly. Today you get -50 reason is changing emoji to the rubbish you have today. Why break something that looked fine?!?! Please give me a button that uses old-school looking emojis please please please Full Review

    I would give this ZERO stars if i could! I can't BELIEVE they DARED change the emojis to THOSE ugly ones! Just kidding. What the f is wrong with you people? Leaving negative reviews because of emojis? Really? Did the whole world turn 12 overnight? Take a second to read and understand they were legally required to do the change. Christ. Whoever the community manager at Slack is, I'm sorry you're having to deal with this, you're a champ though, good luck. Full Review

    Please, just please revert back to the old emojis. Why is every app leaving that perfect emoji pack. This really makes me sad. Now I won't be using emojis anymore and our workplace will turn into a boring and cold place. Full Review

    It's great app. Loved it! Thanks for making it! Just one complaint, slack has changed its emojis, and they aren't much attractive and will take time to adapt ourselves with those emojis. They are quite, aa... Quite bad! Kindly make it the same as it was before, old ones were awesome. Hopefully, this review will be read and replied. Full Review

    I generally adore Slack, but I find it ABHORRENT that they chose to force Android emojis. They allowed iOS emojis until their most recent update, and now the entire communication experience is enormously flawed, like finding a wiggling fly in the middle of your strawberry smoothie. Full Review

    Eats up way too much battery and memory in the background. Like, how you do screw up a basic texting app this badly? You NEED to turn off background activity for this app. With background activity on, I drop 50% in three hours with no notifications from the one slack server that I'm in. With background activity, I drop 10% in five hours with medium usage. Full Review

    It used to be good but now notifications get massively out of sync compared to the web client (e.g. even after reading a message from web, the mobile notification will stay on the phone, wasting 2x time), and also when opening an existing conversation it is often stale and with no way of refreshing it.
