Before signing in to Slack

After installing Slack, sign in with your workspace URL or email invitation. If notifications do not appear, check Ubuntu notification settings and Slack’s own desktop notification preferences.

If you switch between Snap, Flatpak, and deb packages, remove the old Slack package first. Keeping multiple Slack builds installed can create duplicate launchers and confusing notification behavior.
