### 5/5 — To the dev

*2026-05-13*

Hello dev, I bought and gave your application 5 stars months ago.. now after this update it’s constantly asking me to rate it. I have inapp rating OFF for a reason. Please fix this..

**Developer response:** Hi! Thank you so much for supporting the app and for the 5-star review earlier,  I really appreciate it.

You’re absolutely right, and I apologize for the repeated rating prompt behavior after the latest update. I’m already working on a fix to make it far less frequent and respect users who have already rated the app.

In the meantime, tapping “Yes” once should stop the prompt from appearing repeatedly.

Thank you again for reporting this, feedback like this genuinely helps improve the app experience. If you notice anything else, feel free to reach out anytime at support@thegoodcompany.website
