Anyone else get the “please wait a few minutes before trying to import or export settings again” error?

It worked importing the same file to another account, but not this particular one. It gave me the error yesterday, so I gave up and went to sleep. Today it’s saying the same thing. I was thinking maybe the file size is too big? But it’s only 21 kb. =
If nothing else, I’ll keep trying again at a later time. It’s not urgent.

UPDATE: Solved! I guess just try until you succeed. Might take a few days
