Possible disadvantages

    Viber calls and messages are dependent on internet connectivity, limiting its functionality in areas with poor or no internet access.

    Compared to other messaging apps like WhatsApp and Facebook Messenger, Viber has a smaller user base, which may limit its usefulness for some users.
  • Notification Issues
    Some users have reported issues with not receiving notifications promptly or consistently on certain devices.
  • Quality of Service
    The quality of voice and video calls can be inconsistent and is highly dependent on the speed and stability of the internet connection.
  • Privacy Concerns

  • In-App Purchases
    While basic features are free, Viber offers in-app purchases for additional services such as premium stickers and Viber Out credits.

Possible disadvantages

  • Limited Brand Recognition
    Comza is not widely known compared to major competitors like Slack, Microsoft Teams, or Discord, which can make it harder to convince teams to adopt it.
  • Smaller User Community
    With a smaller user base, there is less community-generated content, fewer integrations, and limited peer support compared to more established platforms.
  • Fewer Third-Party Integrations
    Comza likely has a more limited ecosystem of integrations with other popular tools and services compared to well-established communication platforms.

    As a lesser-known platform, there may be concerns about its long-term sustainability, continued development, and ongoing support.
  • Limited Public Documentation and Reviews
    There is relatively little publicly available documentation, user reviews, and detailed feature comparisons, making it difficult for potential users to fully evaluate the platform before committing.
