Starting May 22, 2019 at 5:12 p.m PDT till 10:23 a.m PDT on May 23, 2019 a subset of our users were unable to successfully @-mention user groups.
During our investigation we realized these issues were caused by a change made a few days prior. We had enabled a feature on our end that caused a caching issue which affected user groups. Our engineering team then implemented a fix that resolved the issue.
We’re hard at work on scoping preventative measures to ensure this doesn’t happen again in the future.
