Mango improves the whole WP7 experience. What's truly impressive is how Microsoft integrated all these new features without adding a steep learning curve. It's new yet it fits like the glove you've been wearing all your life.
The problems I've had have been with the Appamundi and TV Show live tiles. I had 2 tasks that would not show up on the Appamundi tile until I went into the app, same with TV Show. The Weather channel live tile also lags behind the current conditions, have to open it sometimes then I realise its not showing the current weather.
I have noticed my Me tile has stopped updating when I get notifications. It was working great before, nodo and mango. When I go to the notifications page in the Me hub, they are there. And Facebook tile messages. It just seems to be the Me tile.
If I go to the Email & Accounts page and sync Facebook manually, my Me tile updates with my messages. Not sure if its my phone or Microsoft push system or Facebook.
Yeah, I would also like to know what's happening with the endpoints, but don't have the energy to do the whole backdoor registry access thing. At least not till they stop working.
All my live tiles, Mango beta and Mango final seem to be working fine. Having a problem with one app, but he is troubleshooting for me (isolated problem on my device). Btw, Flixter only updates once a week so don't expect too much. On some of the other apps, they need to be updated for Mango. For example, CleverToDo now updates the tile with new task counts every night at midnight as a background task. No need to talk to the server. Works perfectly. Weather Channel does appear to lag sometimes, but my guess is it's their servers and not my phone.
