Is йдете just an alternate spelling of ідете or do the two words have slightly different meanings?

[Vinnfred]

It's the same thing as with і/й conjuctions. The meaning is the same, there are two spellings for euphony

[Greg920188]

The hint says to use де, and then marks де as incorrect. I've lost 3 hearts this lesson because Duo is being so unclear about whether куди or де is appropriate.
