iOS Staircase does not appear in Desert Trader on Monday (iOS 1.6.15, no mods)

Category: Mobile – iOS

Details:
I’m using the official version of Stardew Valley on iOS (version 1.6.15) with no mods.
My Mining Level is 10, and I have 10 staircases crafted in my inventory.
I visited the Desert Trader on Monday (verified from in-game calendar), but the option to trade Jade for staircases did not appear.
I tried restarting the game, reloading the day, and going to multiple Mondays, but the issue persists.
It appears to be a bug specific to the mobile iOS version. Please help verify and fix it. Thank you!

Device Info:
- Platform: iOS
- Stardew Valley Version: 1.6.15
- Device Model: iPhone 15

You have to go Sunday, not Monday.
On Mondays, he sells hay.
