I had a scheduled assignment for a given date. My Calendar View showed that date as "blue" even though I had not accepted the assignment. OK. I'd rather it show as 'pending' somehow to catch my attention. Maybe a light blue?
However, after declining the game, the Calendar View still showed "blue" on my calendar, even though an automatic block was created due to the decline.
This can be confusing. I'd like to suggest a different color be used; perhaps purple (red/blue combo).
