  1. investigating Jun 16, 2026, 03:50 PM UTC

    We are aware that some users on the Slack Android app are unable to submit workflow forms that contain a required file upload field. After a file is selected, the Submit button becomes disabled and the form cannot be completed. Users on Slack for iOS and Slack for web are not affected. We are actively investigating the issue and working to identify the root cause. We'll provide an update in 60 minutes or sooner if additional information becomes available.

  2. identified Jun 16, 2026, 04:48 PM UTC

    We have identified the cause of this issue and confirmed it affects a small subset of users on a single version of the Slack Android app. Users on other Android versions, iOS, and web are not affected. A fix is already available and will begin rolling out to Android users tomorrow. We will provide an update as soon as additional information becomes available.
