App problems: doesn't add food

Does anyone else have problems with the app on iOS at the moment? It's really, really annoying. I search for food, chose the right amount in grams, add it, and it doesn't show up in my list. Or I manage to add something, but then increase the amount and change it in the app. And then it vanishes from the list of ingredients.When I look on the website later I see that these items are actually listed in my diary, and thus in there twice.
