We are glad the support helped, and we hope the whitelist and blacklist work exactly as you need. If anything comes up, just reach out. We are always happy to help.
Regarding the rating, thank you for noticing. Sometimes ratings reflect early versions or isolated experiences. If you are enjoying the app, a short review on Google Play would truly mean a lot to us and help others discover it as well.
We hope to have you and your wife as long term users.
Warm regards,
Jim - Maxlab Mobile
