What are some bad UX present in today's popular apps?

YouTube comments.

The upvote/downvote system appears to be near-useless as it doesn't influence ranking like you think it would (it is a factor, but is by far not the only one), ranking appears to be semi-random and only encourages shitposting.

There is also a lack of moderation regarding said shitposting. They clearly have the infrastructure to (wrongly) ban comments at scale like those critical of China, so why can't they use it for good and ban "FIRST!!!" instead?

Old comments were not imported properly. Older videos have comments with the old reply system (@username) but without being linked to the comment it replied to despite back in the day the "@username" bits being clickable so they clearly have (had?) the data to tie the comments together but couldn't be bothered doing their job properly.

A single wrong click will take you to another page and when you go back you lose your scroll position and you can no longer find the comment you were looking at. The infinite scroll/"load more" system doesn't help with that either.

Reddit (and its clones) solved all these problems just fine (at least on the old UI), there is no reason for YouTube not to be able to do the same.

The absolute worst UI is the banking apps when they ask for details of an account to transfer money to:

* The app asks for the account number

* The app asks for the name of the account

* The app never tells you that it won't check the name against the account number.

This is the worst UI ever, because people lose hundreds of thousands of dollars when they don't realise that only the account number matters.

Dragging icons from one place to another on an iphone. It's almost impossible to move an icon from location A to location B without accidentally moving about 20 other icons at the same time, because everything is constantly re-arranging itself in response to the icon being dragged.

Not an app; but whoever designed Netflix's interface wants shooting!

Hard to unsubscribe or cancel something.

I understand as a company you don't want it to be as a CTA, but please don't use shady UX tactics. Such as smaller, lower opacity, hidden buttons, or adding extra steps/clicks than necessary cancel.

Here's my minor nitpick: pluralization of quantities.

There are still a number of major websites and apps that display strings like "1 days to go!" or "there are 2 item(s) in your cart".

Are they afraid of that extra code to build the string properly? Is internationalization a problem for these strings? Who the hell knows. Not everyone has this problem so it can't be because it's not solvable.

When I try to buy something on Walmart.com, sometimes I get to the checkout screen before it informs me that the item can only be picked up at a physical store. If I wanted to see such items, I'd go to the physical store.

Postmates allows you buy food from closed joints. They tell you "The store is closed " after you pay.

Animal Crossings crafting system. I love that game, but not sitting for an hour crafting items one at a time.
