Hi @waldo1001

This is probably due to file parsing but I can't reproduce this issue. Do you get this for all kinds of pages or just specific ones?
I'd need some pointer to move on.

Thanks!

Cancelling the first discovery might have also caused this (low probability). Anyway, the notification is not cancellable anymore as it is a mandatory first step to gather data.
