> I know from my own testing that Google search results still included AMP links for the first week after iOS 15 was released on September 20

I guess the revised explanation would be "random regression in ios 15 safari that affected AMP"

[lolsal]

Why is this a regression in iOS? Changing the user-agent string is not a regression.

[gruez]

As in, a change/feature added to the rendering/javascript engine caused an regression.

Except AMP still loads in Safari 15 if you spoof the User Agent, per TFA.

[gruez]

"regression" doesn't have to mean "totally broken". maybe it's a little laggy. Maybe it breaks in certain edge cases.

[lolsal]

I don't know that I would classify "rendering someone else's feature" a responsibility of iOS 15 or Safari.

[tshaddox]

Perhaps, although "it was just random" is arguably an even worse explanation.
