Hello @lweidenman - welcome to our friendly community. I am sorry to hear about the problems you have been having with the daily calendar. Do you still have other Power-ups (those events listed under the booster wheel icon on the right hand side)? I have not heard that the studio is conducting a test on the daily calendar feature but I will ask the CM (however since they are located in Europe, they are already gone for the weekend so I won't hear anything until Monday).
Sometimes the studio will conduct a test to learn how the players enjoy different features and events so sometimes some people will have access to some things while other people will have access to different events/features and not have any access at all to a certain feature.
In the meantime - can you provide a bit more information? What platform (make and model) are you playing on and what version of the software you are using do you have.
