   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.
