Slack for desktop runs just fine, except the notification time. The Mobile app has a number of issues that need to be looked into: - sometimes there is no notification of the messages and sometimes there are multiple notifications for the same message despite having read the message. - Often, the message that has been read stays in the unread section and doesn't update. - the message prompts get so messed up that they lead to different groups instead of the one for which the prompt is shown.

I'm getting my messages delayed quite often...sometimes the previous messages don't show up, but the latest messages show up. After I close the application and reopen, I'll get the messages properly. Sometimes I do cache clear to fix - but it's annoying to do often. Also, when I check a new message, the notification won't clear indicating that it's read. I use Slack both on phone and laptop. At first I thought this might be due to network issues, but it's not the case.

Could you use the "Send report" option in the app's "Settings - Notification Settings - Troubleshoot notifications" page to flag this issue with us and let us know more about the trouble the app is running into? The option will be under the icon in the upper-right corner if the test doesn't show it.

All of a sudden in the last few days, it has started to hang when I use it for more than 5secs. Since my mobile battery has been draining very quickly lately, I checked the battery consumption stats. It is using 67% of the battery! Guessing that there could be a bug in one of the recent releases. Pls check asap and provide a hotfix pkg if that is the case. I would have to uninstall this app for now.
