Sorry about that - sometimes Google Play doesn’t deliver the purchase notification right away, so the subscription may not appear in the status immediately.
Please email us at info@callfilter.app and the team will help quickly.
To speed things up, include your App ID (in the app: Settings → Subscription management → Get ID) and the email used for the purchase.
If you prefer, you can also send me your purchase email + App ID in a private message here on the forum, and I’ll try to help personally.
