Review for CardBook by Quippy
Rated 5 out of 5 stars
UPDATE 13.09.19 for preview 42.0
Now it works. Full stars for the fast repairs and the nice contact!
From 06.09.19 on 41.5
This is a greate tool but with version 41.5 on Thunderbird 68 I receive error 503 with nextcloud. This was not the case with earlier versions on thunderbird 60.*
CalDav on Android still works, so I assume a problem with cardbook.
