Notification pausing

I don’t like the notifications automatically pausing. In my line of work, open lines of communication are essential. If I miss something or don’t respond to something because my notifications are paused, it could very well cause potential harm.

I enjoy the platform but I never get my notifications

I’ve recently joined a group who uses slack very heavy. The app with randomly decide to stop giving me notifications every other week. So I run the test. It says it’s fine. I’ll delete the app twice with no changes and then notifications start again the following week. I’ve contacted support multiple times. I’m not sure what else to do

Doesn’t work well.

Switched to Microsoft Teams for my 28 people company and we’re better off. Slack lacks in every department.

Mostly good

Huddles are a nice addition, but they should be better integrated w/direct “calls”: - allow switching from call to a huddle - feature/UX parity - allow “calling” someone from w/in huddle (“calling” gets the invitee’s attention, whereas huddle invites are too subtle and easy to not notice) - better window management on desktop when a huddle or call screen share window is open


- dowmload app - enter email address - receive email - click confirm email - opens a webpage in a browser that says i should download the app

Better if
Ms Melg

My experience with slack has been good. It would be even better if I were able to turn slack off completely when I’m away. I can set my status in away and log off however messages continue to come through and people still slack you in away mode if I were able to fully turn it off as not to rcv any notifications until I log on this would be better and improve my experience with this app.

Used to be fantastic

We use this app for work and it is great. But lately I have had multiple issues where my multimedia messages refuse to send and won’t allow me to retry. I’ve reinstalled the app multiple times.

Can’t upload

I can’t upload any documents all morning, not only me, all my team members has same issues, I don’t know why it’s taking to long to fix I will say poor customer service from slack

Let me leave a convo / group

Can’t leave a conservation or group. Someone can forcibly bring you into a group.

Profile Picture Glitch

Slack really needs to fix the profile picture glitch. My colleagues and I’s profile pictures will often clone the profile picture above it in a slack channel. It’s extremely confusing in long conversations.
