The fact that you want me to download…
The fact that you want me to download an app to track the package I paid for is highly suspicious. You've lost my business going forward. You want to turn your customers into a product to sell to an app company? DO BETTER. Update: the item which was listed as in stock didn't ship after 2 weeks. I received an email stating that it might ship in a week and a half, so I had to cancel. Ordered for same price from another supplier and received our filters within 48 hours. Voltage is a scam.
