Slack Mobile Push Notifications Stop Delivering Mid-Day Without Warning
Slack mobile notifications fire reliably for a period then silently stop for the remainder of the day, causing users to miss messages entirely. The failure is intermittent and non-obvious, making it difficult to diagnose or work around. This is a critical reliability gap for remote teams depending on mobile alerts.
Slack Notification System Misses Channel Activity Without Direct Mentions
Slack only sends notifications when a user or channel is directly mentioned, causing team members to miss important updates in active channels they follow. This affects distributed and async teams where staying informed without constant monitoring is critical. The notification gap forces users to manually check channels, undermining the value of a real-time communication tool.
