A payment can fail for a few common reasons:
Insufficient funds or a card that's expired
Your bank blocking the transaction as a security precaution
Outdated billing details (card number, expiry, billing address)
To fix it: update your payment method in your App Store, Google Play, or client-pomospeak.personalized.app account settings, then try again. If the issue continues, check with your bank, or email pomospeak@personalized.app.
