incorrect import from GR takeout

I tried to import my categorized feeds form googlereader takeout subscriptions.xml file. Only the ucategorized feed were imported.
does FA support categorized feed import?

Fixed

OPML import did have some errors and categories could be affected. It's fixed now and should work.

How many levels of categories

How many levels of categories did you have? I haven't tested it recently, but it used to support a few nested levels. I'll have to go back and test it out again.
