On January 30 at 8:40 PM PST, we internally detected an issue where customers were unable to sign into the Android app through Single Sign-On. Upon investigation, we determined that the issue was related to a recent browser release. On February 1 at 3:29 PM PST, we implemented a fix, so all customers should now be able to sign into Slack on their Android devices. If you are still having trouble, please let us know at feedback@slack.com.

We believe to have narrowed the issue down to users on Chrome version 72. We do however have a workaround for the meantime. If you’re facing this problem, please try the following steps:

1. Open a mobile web browser and navigate to your workspace URL
2. Tap 'Sign in with [your identity provider]'
3. Enter your username and password, then sign in
4. Once signed in, tap 'Open Slack' under 'Have the app already?' to launch your workspace

We've identified that this affects some Android app users signing in with their identity providers on Grid. We're continuing to investigate the issue.

Some customers may have trouble signing in to the Android app through their identity provider. We're very sorry for the disruption — we're on the case.
