Trade in value for iPhone 8 with broken back glass
The glass on my iPhone 8 is broken in the front and the back. But besides that the phone functions perfectly. Can I trade my phone in for an Apple gift card through the trade-in program? I took my phone to an Apple store and the associate working there says that Apple won’t except phones for trade-in value if the back glass is working. Based on what I’ve seen online, I’m not sure if the associate is correct. I need a definitive answer, please
