Slack has issues with notifications and loading threads and channels

If you’ve had issues with Slack, you’re not alone – the the status page of the service reports that “something isn’t right” with messaging, apps, integrations, APIs, and connections. The issues, which appear to be affecting threads, channels, notifications, and group DMs, started around 9:40 a.m. ET this morning and are still ongoing. Slack says it is “actively investigating”.

Hereby The edge, the problems seem to manifest differently in different people; one of my colleagues described Slack as “funky all morning”, noting threads in particular, while another reported that their notifications weren’t displaying correctly and threads were loading randomly. For me, the app sometimes crashes when I try to load a channel, and I can only scroll back a certain amount; the app also launched me from the Threads screen when I tried to type a reply and then didn’t show hours old threads until I went back. Another colleague reported that their Threads screen was completely broken.

While these issues are annoying, they aren’t quite work-breaking like complete Slack outages. That may be why it’s not talked about much on Twitter and why there are relatively few reports on But no, you’re not imagining it’s not quite right; hopefully Slack will get things sorted soon.
