Where can I find the uploaded files?

If Uploadly was correct setted up and the theme is compatible you will find the uploaded file directly inside the order view of Shopify.
You will see a blue highlighted link, by clicking this link you can download the file from your customer.

Please note: You can receive files just with the regular Shopify Checkout. External Checkouts will not work.

You can not find the file in your order? 😅
