frustrated

Hi, Aymeric, I don't know why, but I just upgraded and it won't respond to several commands: I click on the right arrow and it will not take me to the following week; I enter a new role and try to place it on a specific day and it won't let me; I entered new roles, went back to the previous week, and had to reenter them all again because it didn't save them...I hope it has to do with my end and not yours...
