Hi, I have the exact same problem
The first day the daily tasks didn't work for me. And that was solved.
I completed the first Dr. Vu mission and for a whole day I couldn't move forward with the second mission because simply clicking on "Chicago Missions" brings me back to the game, without opening any windows.
Today I noticed a green clipboard in my capital, and I discovered that it contained the second Chicago mission. "Great" - I thought - "it will be a temporary solution and now they will fix it". Too bad that once the shovels are produced and the popsycles are collected, the third task, the expeditions, doesn't work.
What frustrates me is that I regularly spend money to buy the premium pass for the CoM, but not only will it be very unlikely to get the "Riverwalk" with the new limitations imposed (and therefore the gothic tower), but with these problems it will be completely impossible. How am I supposed to collect enough seasonal coins? And then why put a 60k shop and be able to collect a maximum of 30k by completing all the missions. And what if I was also interested in other buildings?
You should rethink what you are doing. I'm not saying that the new changes are all bad, and I'm not even complaining about the malfunctions. I think, however, that you should enjoy playing SimCity, and more than fun it is becoming stress, or a job. And this is not good, and it's a shame.
