왜 관리자 계정에선 프런트 엔드에서 테마를 변경할 수 없나요?

Yes, correct.

Yes, my admin account, the only admin account, cannot.

Yes, I just use it as a demo because on my own site I don’t have it when using my admin account.

I have two themes.

Never mind this thread; the dropdown is shown now.
I guess it just needs a hard reload.

All’s fine now.
