Duplicate of #243. At the moment, DAVdroid doesn’t check for deleted or new collections but synchronizes the ones set up.
Setting color of single events discarded after sync
With Business Calendar it is possible to assign colors to specific events independently from the overall calendar color. After DavDroid sync, the individual colors are discarded. I disabled also “Manage calendar colors”, but I don’t think this is related.
Is this a (intended) behavior on the DavDroid side? Or just an issue on the Business Calendar side?
Please follow up at Single-event colors are reset when syncing.
