The latest version of MyAppSales contains a fix for times when iTunes Connect is offline, but the ITTS reporting site is still running.
This way you still get your daily sales reports throughout the downtime for ITC which was announced to go from December 23rd until December 29th.
Another minor change is that review scraping no longer is requires for the app totals to be loaded because all reviews for all apps are scraped at the same time anyway. This is a minor startup speed benefit.
Merry Christmas and Happy Holidays!
UPDATE Dec 26th: Apple caught up on using the ITTS url for report downloading and shut this down as well, giving this message.
So, there now really IS no way to get to your daily reports anymore. We all have to wait until Dec 29th.
