Yeah, I am just not sure what the heck to do. I mean how are other people logging in to view the IHS site if we are all using the same application process?
Because you may not all be using the same process - the process is different in different countries and is different if you apply by post vs. online. If you're applying by post, then you go to that site and create an account to pay it, but if you're applying online, you pay it during the online application process.
Alternatively, if you are exempt from paying it you will still need to generate an IHS number online even if you don't pay, while some visas don't require an IHS number at all (i.e. visitor visas, fiance visas etc.).
If you're applying in Bangladesh, Myanmar or the Democratic People’s Republic of Korea, you have to pay the IHS in cash at a visa application centre, while in Nepal you can either do it in cash or online.
There must be a way to find out what the information is or how to create and then link the reference number somehow?
Seriously, stop worrying about it - you should already have the IHS reference number on your application.
Just explain what happened in a cover letter and send it to Sheffield with your documents. If there's an issue with it, I'm sure UKVI will contact you.
