I have two caldav synced servers with multiple calendars each. As the server supplied colors collide, I simply override the colors in the calendar app. That used to work fine
Since upgrading to 4.0.1.45 EA, while I can still change the colors in the app and the changes get properly propagated to other views like the events view, they change back to the server supplied colors after re-syncing or restarting the calendar app. I presume the later triggers a resync, so that may be the same technical issue.
Is that already a known issue? I wouldn’t know where to look for it. But it’s a tad bit annoying
