Did you edit these files?
Thatās the strange this, @cgrunenberg : no!
I did open them though (or try to) so as to check which app they would open with. But, really, that was after theyād changed from TaskPaper to MindNode!
Are the problematic files still only ones youāve put in the Reading List, i.e., other imported ones arenāt showing the behavior?
So far, āChange allā seems to have worked for files in their ārealā Group as well as in the Reading List.
Iām keeping on looking every few hours to see if they have ārevertedā anywhere. Will report ā¦
Thanks!
It really does look as though this has been solved by selecting āChange allā for any single TaskPaper document (including those in DTās Reading List).
Very many thanks to everyone who has helped me here!
Case closed ā¦
