What's New in Smack Tax Lifeline

Verified odometer readings now attach to the trip you're actually on. When you capture a verified odometer photo while a trip is still recording — engine running, before you shut off and walk away — the reading now pins to that active trip instead of the previous one. Before, if the trip was still saving when you scanned, the reading could land on the last trip and throw off its odometer and mileage. Pinned to the active trip at the moment of capture. That link is locked, so later automatic corrections can't move it back to an older trip. No change to your mileage or tax numbers — this only fixes which trip a reading belongs to.
