@devvv4ever I am aware that I should disable any power saving things (if I could only ever be sure I didn’t skip over the relevant one - different story); with the question I just meant that, when I encounter sync issues on that device with this specific topic, any changes to those appkiller settings currently will now help as long as the issue described above is not solved. That is, I understand by now that the missing sync setting items is not just a minor layout issue but actually reflects a disabled sync.
Could not create account: Invalid DAV response
I want to sync with Horde. While creating an account (base URL mode) I get an error:
Missing capabilities: Invalid DAV response: 207 Multi-Status expected but not received.
Fix: I found out that if I don’t use my email address as username but the postbox username I could proceed and sync.
Remark: If I enter the base URL in a browser I could successfully login in with my email address and see the SabreDAV webinterface.
Ok, thanks for the info!
