Today, the behavior was quite different, it didn't work either way.
I was in Version 6.0.19 on my laptop with no Shearwater Desktop installed and I was not able to transfer any dives.
An update to 6.0.20 didn't help.
The funny thing is, that I get multiple error codes
- DC_STATUS_IO something
Afterwards an import from the Shearwater database was possible.
That is so strange...
