The delay is almost assuredly to prevent live scamming. Like a grandparent picking up a random call or text and being tricked into thinking they’re a family member/bank worker/etc.

Taking their explanations in good faith and looking at it from an customer security point of view, I can see this cutting back on some common scam types. This is kind of like how, when you go to rustdesk.com there’s a giant ‘YOU’RE PROBABLY GETTING SCAMMED’ banner across the top of the page:

These little steps can seems pointless or annoying to us, as most of us are probably in the upper range of tech skills, but consider the average user and it starts to make a lot more sense.





It is simple, it is not easy.
‘Take a picture of the entire ocean and look for ships’ is simple, but executing that plan is not.
It requires hundreds of millions of dollars of reconnaissance satellites, and an entire branch of personnel to operate and digest the information.
This is why the US operates carrier battle groups instead of just sailing their carriers everywhere with a small escort. They can’t hide, but they can pack enough offensive and defensive power into a tiny area to make most attacks infeasible.
True, and even they’re vulnerable when they surface (if they’re moving), the v-shaped wake is also very detectable from space where satellites can detect wave heights within 3cm. It’s not easy for humans to find, but with billions of dollars to spend on computers, these kinds of things are very much within the reach of sovereign nations.
