        Hi,
do you know what had been updated, please? Was even evolution or
evolution-data-server packages updated too? Does it help to downgrade
it/them?

I think there was some UI glitch which showed the path as None even it
had been properly set in the background, but it's a long time since
3.12.9 (the current stable series is 3.28, if you wonder), thus I can
be wrong.

It's the path in the corresponding .source file which matters the most.
When you run evolution from a terminal, does it show anything? I mean
like a runtime warning, not anything with enabled debugging. You can
try to right-click the folder name in the left folder tree and pick
Refresh there, even couple times, if it's available in your version.
Also, checking content of the newly created folders.db file may give
you a chance to see whether evolution(-data-server) found the mails. If
it's there, then you might have set some filter in the Evolution view
for that folder. And as there had been another glitch in the past,
which made it look like the folder has no filter, but it had been
filtered anyway, I suggest to do some filter, like "Subject contains
a", and then clear it.

        Bye,
        Milan
