Fix Signal Reconnection Captcha

I am looking for an experienced developer to address a recurrent issue I face with the Signal app. Whenever my connection changes, such as when using a VPN or BlackBerry Connectivity Node, I'm prompted to complete a captcha for security verification. Though it's a security feature, the frequency of these prompts disrupts my app usage. Here's what I need:

- Diagnose the frequent captcha trigger after reconnections
- Develop a solution to minimize unnecessary captcha prompts
- Ensure the fix maintains user security without compromising the user experience

Ideal skills and experience for the freelancer:
- Proficiency in mobile app development and troubleshooting
- Experience with Signal's codebase or similar secure messaging apps
- Strong understanding of VPN and network connectivity
- Knowledge of captcha implementation and security measures
- Ability to provide a seamless solution without degrading app security

Please reach out if you have the expertise to solve this issue effectively and efficiently.
