A phrase meaning a drawback turned out to be an advantage [duplicate]

I remember having heard one before but can't say how it went. The phrase says that what initially seemed like a disadvantage — became an advantage.

If anyone knows anything even similar to this definition, it'd be much appreciated.

Solution 1:

You are probably referring to a blessing in disguise

something that seems bad or unlucky at first, but results in something good happening later:

Losing that job was a blessing in disguise really.
