To do list not refreshing

It should refresh after a day...
When you begin playing the game on the new day, do you see the animation where the moon sets and sun rises? Do you get the login rewards and overview of the stickers your sims got?

I haven't had any problems with it switching over to a new list each day and I log in every morning right after I wake up. I get the Moon to Sun animation and then it shows me the log in rewards, overviews of the stickers and then the new list is available.

Try completely closing out the game. And if that doesn't work close out the game completely and try shutting your phone off and turning it back on again and logging back into your game.

My to-do list did not refresh, most probably because I came back to the game the following evening, not during the day. Today I did come back in the morning and it refreshed this time. So probably login during the daytime... But it should be implemented so that it refreshes on the following day, no matter what hour you come back.
