Request to Increase Connected Athletes Limit (Error 403)

Hello Strava Team,

I am currently developing an application to manage and track activity logs for athletes in my running club.

The application works correctly for the first athlete who authorizes it. However, when a second athlete attempts to connect, I receive the following error:

Error 403: Limit of connected athletes exceeded

Could you please help review my application and advise on how to increase the connected athletes limit?

My Application Client ID: 135639

This app is intended for internal club management purposes only, where multiple club members authorize access to their activity data.

Please let me know if you need any additional information about the application.

Thank you very much for your support.

Best regards,
Nguyen Hai Thanh
