Hi there! I’m Emily from Digistore24 support. I understand you’re having trouble changing your shipping address and can’t find your order in the Digistore24 app on your iPhone. Let’s work through this together.

First, just to clarify:
- Are you logged into the correct account that you used to place the order?
- Could you tell me if you are searching for the order by order number, or looking through your purchase history?
- Also, have you tried checking your email inbox for the order confirmation? That can sometimes help locate the order details.

Here’s what you can try step-by-step:

1. Verify Login: Make sure you are logged into your Digistore24 app with the right account email. Sometimes orders won’t appear if you are on a different account.

2. Check Purchase History: In the app, go to your profile or account section, then to "My Orders" or "Purchase History." Your orders should be listed there.

3. Search Order by Email: If you have the confirmation email, it usually contains a direct link to your order and sometimes lets you update your shipping info.

4. Changing Shipping Address:
- Normally, Digistore24 allows address changes within the seller’s policies timeline. If the order is recent, there might be an option within the order details to modify shipping information.
- If you do not see this option, it might mean the seller does not allow address changes after purchase or the order is already processed.

5. If the Order is Missing:
- Double-check the email account used for purchase confirmation—sometimes orders are placed under different emails.
- Try searching in any linked accounts if you have multiple accounts for Digistore24.

If after all this you still cannot find your order or update the address, please let me know. I can guide you on contacting the seller directly or how to send an inquiry to Digistore24 support for further assistance.

Could you please try these steps and tell me which ones you have done or what you see? That way, I can help you better!
