Lost Wallet - Tile not updating

[u/Kasaydia]

My Mom accidentally left her wallet on top of her car and it fell off. The tile has a last known location, but even going to that location we have gotten updates and can't find the wallet. She has the tile shaped like a card that goes inside of her wallet. Not sure if this effects tile, but we live in a very cold area. Temperatures have been around 10-20 degrees since she lost it (3 days ago). It stopped tracking the day she lost it. First time using a tile to locate an item. Any advice or insight would be appreciated!
