What does the "Billing Issue" email mean?

If you received an email from us with the subject "Billing issue" or "Action required: Your billing issue", it means we were unable to process your subscription renewal payment.

Why this happens

The most common causes are:

• Your card has expired or been replaced
• Your bank declined the payment (banks sometimes block recurring charges)
• Your payment method has insufficient funds
• Your card details in the App Store or Stripe are out of date

What to do

If you purchased through the App Store:

1. Open Settings on your iPhone, iPad, or Mac
2. Tap your name → Payment & Shipping
3. Update your card details or add a new payment method

Apple will automatically retry the payment. No further action is needed once your details are updated.

If you purchased through our website (Stripe):

1. Go to the Linearity Billing Portal
2. Log in with the email on your invoice
3. Go to Payment Methods and update your card

Your subscription will renew at the next retry attempt.

What happens if I don't fix it?

If the payment continues to fail, your subscription will eventually be cancelled and your access will revert to the Free plan. Your files are not deleted — you just lose Pro features until you resubscribe.

Already updated your card but still getting emails?

Payment retry cycles can take 24–48 hours. If you've updated your details and the problem persists after two days, contact our support team.
