Why are the colors from of the legend in the calendar gone?

Question

The items in the calendar legend used to have the same colors as the corresponding entries. Now the legend is completely gray, and colors are only visible in the calendar, making it impossible to match entries with their corresponding topic at a glance. What could be causing this? I am using version 9.1.1.

The post is already here since January, but still no solution, nor guidance. Is there really no solution for this issue?

Same here. I have teams of 30 people across the world accessing these calendars - they worked great! After the update this week, no color at all appears on the legend, which makes them useless.

Please address this fix as soon as possible.

And same here - so annoying. I have a view with 3 different calendars, I had set up nice bright colours to have a very easy overview all in one, and now everything is in greyish type of colours ... and no way anywhere to adapt those or change those back to what they were before ...
Any ideas how to fix this?
