I recently tried to modify a contact that is on a CardDAV server hosted by Fastmail.fm. However, whenever I edit a field and save, I get an error: Failed to upload item “Test Contact”
Some testing details:
- It seems that I can create a contact and modify from eM Client with no problems, but if I create or modify one directly in Fastmail, I get this error every time I try to modify it from eM Client.
- I have can delete the contact with no error
- I have two different computers with eM Client, and both have this problem
- I can successfully modify contacts from my Android phone connected to the CardDAV server.
