Is Slack Not Working? App Experiencing Issues With Threads, Links and Notifications

The workplace messaging system Slack was experiencing widespread issues with threads, links, notifications and other functions Friday, the app confirmed. In an afternoon update, Slack said it was "working hard to fix this as quickly as we can."

"Our apologies for the interruption to your morning," Slack said. "We are seeing some issues with unfurling (link preview), notifications, message threads, apps and integrations."

The issues were first reported on the company's outage detector about 12:05 p.m. EST.

It's the second time this week Slack has seen large issues. An outage Wednesday due to "connectivity issues" affected all workplaces, causing problems for everyone using the messaging system.
