Monopoly Sudoku

Many issues in Monopoly Sudoku.  Some of these I've reported before, but there's been no resolution.

1) Collecting rent earned offline: The first time you start the game, it takes over a minute for the offline earnings window to display.  When you click on it nothing happens.  I waited a couple minutes before refreshing the window.  This takes you out of the game.  On re-entry, the offline earnings window displays quicker, and it awards the rent to your overall total, but not to the daily target. 

2) When you click the check mark after an upgrade, the animations are quite slow.  if you have more than one upgrade, it takes up to a minute to go from one to another. Sometimes you get the 'unknown error' box. Eventually the appropriate stars are awarded, but it takes much too long.  Sometimes after you get the 'unknown error', it stops and you have to refresh.

3)  Chance cards:  Many times, the first time you go into a game and fill in a chance card square, the cards don't display and you don't get to select one.  It lets you complete the sudoku squares, but it won't complete the game.  You have to exit and start over.  See attached screen sample.

4) Daily target.  When you earn enough to meet the daily target, the chest is empty. 

5) Collecting rent.  When you click on the money bag to collect rent, it takes over a minute to add to the running total. It doesn't appear to add to the daily target.

I am running on the latest version of Firefox.  I cleared cache and that has no effect.  I can't even get the game to load under Microsoft Edge.
