My favourite example is Airdrop. It never ever was reliable for me, hidden problems made it inoperational between changing combination of 3 apple products (2 MacBooks and one iPhone) most of the time. Mostly it does not work. The other device does not appear on the 'radar'. Even when works then one file at a time, choosing 3 options for each single one, e.g. transfer 4 pdf I require on the road for travel, drag only one (4 at the same time is refused), accept teansfer, select where to put it let's say files, then select where in files. repeated 4 times. Not even remotely user friendly or making life easier as it was supposed to. But if you have a picture (e.g. screenshot you have no choice at all, it decides that it WILL go among pictures, that's it! Right now I only can send files from one Mac to iPhone but not the other way around. It was working two ways before until an update on one of the devices, don't remember which one. And remained so even after repeated updates on both (one is an old SE so that may be just behind features or what, but I don't care why! I am not for my f.g phone but the other way around! I paid for it to help me not for solving mysteries! It should just work but it just not!)
