Lost iphone X in waterproof pouch

[Busykiel]

I lost an iphone X (grey) probably somewhere around 9:30/D headed up 9:30 to 9:45/G.

I searched for it on the streets as soon as I realized it might have dropped, since I had it at 9:30/D where I checked the app for directions to the ice cream camp at 9:45/G... but no luck.

It may not be in the pouch anymore, but that’s what I lost it in. The pouch is larger than the phone and has blue plastic strip at the top with magnets to seal its contents.
