BMP App Beta Version

On the Create Account screen, there is no proper validation for very long input values:

• Username field allows excessively long input without restriction
• Phone number field also accepts very long numbers beyond valid limits

Steps to Reproduce

• Open Create Account screen
• Enter a very long username (e.g., 100+ characters)
• Enter a very long phone number
• Tap Continue

Actual Result

• System accepts very long username and phone number
• No validation error is shown

Expected Result

• Username should have a maximum character limit
• Phone number should be restricted to valid length based on country format
• Proper validation errors should be displayed
