We will likely not be able to precisely sync up the analytics infrastructure release with the LMS release, so there will be a period of time when either:

1) Reports will appear here without any explanation
or
2) An explanation will show up here, but no report

I see both as being negative enough to warrant a generic statement like this to bridge the gap, but I'm OK with removing it if you disagree.  Either way I suppose I should put it in another translation block so that the string isn't invalidated while we are changing it frequently.
