I have the problem with a calendar (standard, CalDav) that I cannot change the colour. Or rather. I can change the colour and after about five seconds the colour jumps back again.
Any idea how I can switch this off?
Background: When I set up my standard e-mail account, the parallel setup of calendar, contacts and tasks was not offered. I have therefore added them via CalDav/CardDav and stored them as default folders in the default e-mail account.
