Reproduction:
Create an OPML file. (In this case one from Dynalist)
Attempt to upload.
Result: Get an "importing" message and nothing further.
Why this matters: Importing OPML is a key vector to migrating on to Legend.
See screenshot and example opml file content (attaching didn't seem to work):
<?xml version="1.0" encoding="utf-8"?>
