Is that what the generic email looks like .. it is worded odd, not really sure what it says 
Yes, that's the generic email - it reads weirdly because it's aimed at people applying from all countries, but each country has its own application process.
In a nutshell:We have your application and it has been put in the waiting line. It might take up to 12 weeks to process, but priority applications will normally be processed faster.
Longer version:Paragraph 1: We have your application and it has been put in the waiting line.
Paragraph 2: submit your documents in this order, if you haven't done so already and if you are not in the US or Canada
Paragraph 3: ignore paragraph 2 if you have already submitted your documents
Paragraph 4: we aim to process applications within our service standards time. If we can't, we'll send you a 'non-straightforward' email
Paragraph 5: If you have paid priority, your application will be put to the front of the line and should be processed more quickly, but if it is considered non-straightforward, it could take the full 12 weeks
