Note that you have forbidden French, but have allowed "Simple English" which is definitely not a priority (standard English is already in the source, and there's actually no real need to "simplify" it in this translation request).
In general all major linguas francas (spoken in many countries) should be enabled in all translation requests, even if it's not the final intended target. And anyway this page is important for all languages, not just minority ones, as it is about a new general feature.
As the result, you'll get translations ONLY in countries where English is widely understood as a official, regional or native primary/secondary language, and widely taught in schools with a good skill level. This request won't work like you'd like in South America (except possibly Argentina but you don't have any minority language listed for that country), India (English is secondary, Hindi is official, but many people cannot read English and translate it correctly to their regional language), South-East Asia, Western/North/Central Africa. And where another major lingua franca is used (French, Spanish, Portuguese, Arabic, Chinese), English understanding translation skills are largely underdeveloped.
