## Review summary

Multiple users report that recent updates to ServiceMax Zinc have caused frequent crashes, lag, and usability issues. Logging in problems are common, especially with Salesforce integration. Notifications have become annoying, and some features like deleting messages are missing. Despite these issues, the app enables communication in restricted regions and integrates with Salesforce, which are its key strengths.

### Pros

- Allows communication in regions where other apps (like WhatsApp calling) are banned.
- Integration with Salesforce for business communication.
- Supports sending photos in conversations.

### Cons

- Frequent app crashes, especially after recent updates.
- App becomes slow, laggy, and difficult to operate after updates.
- Problems logging in, particularly with Salesforce and email acceptance issues.
- Notification handling has worsened, with notifications sent per message rather than per thread.
- Limited functionality for managing messages, e.g., cannot delete messages, only archive them.
