Ah, that explains it. We went to Mallorca last year (from Iceland where I've lived for a few years after leaving the US) and I was SUPER excited about McD's breakfast, only to find they sold nothing but burgers :(

Yeah it's sad, I agree. Their breakfast is lovely, and it was one of the few places to get something like this, most places serve more Spanish style stuff like a sandwich with a potato omelet in between. In fact McDonald's even had their own version of this one too. But they also did the usual ones.

Gone entirely or just no longer served all day?

In America, Covid killed the "all day breakfast," which is a shame. Sausage and egg muffin is better than all their lunch/dinner food.

Meanwhile in Canada we got to keep all-day breakfast, but lost out on a handful of only-at-breakfast items. McGriddles were gone, but came back around January of this year. Breakfast McWraps were also taken away but haven't yet returned (far superior to Tim Horton's farmers wraps, IMO). Otherwise I don't think the lunch/dinner menu changed at all.

Gone entirely. Here in Spain it was never served all day. Until 10:30 or so they served only the breakfast menu and after that only the regular one.

So now it's the regular menu all day. Big mac for breakfast? Hmmm. No.

In fact I've never seen all-day breakfast at any McDonald's in Europe and I've traveled a lot for work (so a lot of hit & run breakfasts at airports)

We still have all day breakfast out in Seattle, just not the full menu. My go to is sausage patty, round egg, yellow cheese.

Yum yeah... That's the one I miss!

I always wondered how they get the eggs so round but one time I saw them make them.. They fry the egg on the burger plate but in a metal ring. Cool idea.

what the hell does COVID have to do with the all-day breakfast though? How does cancelling it in any way mean anything for COVID policies or spread?

It doesn't. For a while the Mcds near me had a reduced menu, probably because they had less business and a reduced menu was easier to maintain. But it's back to normal now, including all-day breakfast (Canada).
