Issue summary: From 11:15 AM PDT to 12:54 PM PDT on August 1, 2022, some customers may have experienced 'invalid_auth' errors when interacting with apps, integrations, and workflows in Slack. A code change earlier in the day inadvertently introduced a caching issue that caused the 'invalid_auth' errors. We rolled the code change back to mitigate the impact, then deployed a fix to resolve the issue for all affected customers.

We've resolved the issue: impacted users should be able to connect to third party apps and integrations, and use workflows once more. If you're still encountering trouble, please reload Slack, by pressing Command/Control + Shift + R. We apologize for any disruption to your work day.

We’ve begun rolling out a fix. We’ll return with another update once rollout has concluded — thanks for your continued patience.

While investigating we found workflows are also impacted. The good news is we’ve identified a potential fix which will be rolled out soon.

We’ve received reports of users running into 'invalid_auth' when using apps/integrations. We’re investigating and will let you know as soon as we have further information to share. We appreciate your patience in the meantime.
