Did you try using it?

I’ve applied for evisas to India multiple times, it’s extremely buggy and many times you’ll have to start again from the beginning… additionally, their payment processing is often not functional so you have to keep retrying the payment…

Once the visa is applied for, the process is usually quick.

Part of the way. I didn't want to give them my personal data or money as I have no plans of visiting India.

I had a similar experience last year applying for an evisa. I think pay off the issue was related to the pages timing out before the extremely slow server somewhere in India could process the query and respond. My relatives on their iPads and few year old mid-range dell Inspirons could not manage and had to consult me for help.

I never had a problem with applying for an evisa myself - including stopping midway and using the resumption token thing. There was an awful lot of stuff to fill out, but thats a legal thing, not a web design thing.

I do remember feeling the payment process was a little sketchy, but it worked alright
