Access is granted per number, not account-wide. Check that all team members have the Quo, formerly OpenPhone, app installed and notifications enabled. Ensure they're logged into their accounts on their devices. Only account Owners and Admins can add users to phone numbers. Verify your role permissions and ensure you're using a supported platform (web, desktop, or iOS). Internal threads are only visible to users who have access to the specific phone number. Ensure all relevant team members are added to the shared number. Check your plan's user limits (10 for Starter, 100 for Business). Consider upgrading your plan or redistributing users across multiple numbers.
