Zoom Team Chat channel Integrations shows ‘No apps’ (no Add Apps button) + ‘Failed to add apps’ when adding custom Marketplace chat app (Free account, macOS 7.2.2)

Hi Zoom Community,

I’m an admin on a Zoom account and I’m trying to add our custom, account-level Zoom Marketplace Team Chat app to a Zoom Team Chat channel.

Account / client info:

• Account type: Basic (free)
• Zoom desktop client: 7.2.2 on macOS

What works:

• The app is installed at the account level and works in 1:1 DMs.
• The app is set as Admin-managed.
• The app has the required Team Chat/chatbot permissions/scopes.

What doesn’t work:

• In any Team Chat channel (including a brand-new internal channel), the channel’s Integrations tab shows: “No apps”
• There is no “Add Apps” or “Manage Apps” button.
• If I try to add the app via the @ mention / plus flow, I get this error: “Failed to add apps. Please try again later.”

Additional notes:

• This doesn’t seem specific to our custom app—no apps appear available to add to channels at all.

Questions:

1. What account-level admin setting controls whether channel apps/integrations are available in Team Chat?
2. Is there any plan limitation for Basic/free accounts that would cause the Integrations tab to show “No apps” with no Add Apps/Manage Apps button?
3. Any troubleshooting steps to resolve the “Failed to add apps” error when adding apps to channels?
