3 problèmes principaux

Hello to you,
I have some problem that arrived about 1-2 weeks ago (before everything was fine). I have to be the only surviving player on the phone to play on minecraft and therefore I can't find anyone else with these issues. (I try to make all the successes of the game in my survival world)

1st problem:
What I expected was ...:
Unlock successes in my world (stay 1 day underwater, collect honey, slide on a honey block to avoid falling damage, craft a cake ...) even if I have NEVER activated the creative mode or cheat.
What really happened was ...:
NOTHING ... I stay more than the official 20 minutes (1 day in minecraft = 20min ~) underwater, jump, slide on a block of honey so as not to have fall damage and after that, recover honey with a campfire below, no successes appear

2nd problem:
What I expected was ...:
I wanted to make a classic cake (milk, egg, sugar and wheat) to place it, eat it and have success.
What really happened was ...:
As soon as I place all my objects in the craft table and I click on the castle to retrieve it, it disappears and does not arrive in my inventory, even if it did use my 3 wheats, 1 egg, 2 sugars and milk ...

3rd problem:
What I expected was ...:
After crafting my cake which never arrived, I wanted to make it again with all the ingredients by making it.
What really happened was ...:
I take sugar cane and transform it into sugar but it drops, same for blocks of wheat to have wheat, they drop at my feet while I have room in my inventory.

I turn off my iPhone, I make the last update of the software of my phone (because I had a later one) or to "unload" the application, these problems do not disappear.

Waiting for your return

Thanks for your help
