for who is having my issue, I confirm that this one:
solved entirely
my issue and that after last upgrades the ics was here
~/.local/share/akonadi/file_db_data/32/32_r0
where 32 is only the # number of note, so change it to what you have into
~/.local/share/akonadi/file_db_data/
very interesting, I found there all the release of the notes, old stuff that
can come back useful one day
as always, you guys are very helpful and fantastic :)
this community is great :)
