wish they didn't insist on using the most formal way of writing for everything

[Okawoa]

absolutely. 나는 비싼 음식을 먹어요 should be accepted.

[Staffan431948]

Only they don't. Sometimes it's supposed to be informal for no apparent reason. I just wish they could stick to the one or the other.

'나는 비싼 음식을 먹어요' why isn't it accepted? It's correct though...

[tehjuneee]

'저는' 빼고 그냥 '비싼 음식을 먹습니다' 도 맞는 답입니다잉.

Just '비싼 음식을 먹습니다' without '저는' should also be accepted.

Wow... I'm seeing comments from four years ago mentioning this issue of the less formal form not being accepted even though there is no indication of what the speech level should be. It's incredible that Duolingo still hasn't gotten around to fixing this issue when I'm sure many people have reported it in that time. 나는 비싼 음식을 먹어요 should be accepted but still is not (written March 5th 2022)
