Microsoft has acknowledged the Windows Phone 7.8 Live Tile issues consumers have been experiencing



From WPCentral:

Developers have approached the company with reports that problems have been caused by the magic tiles, with a MSDN forum thread prompting a response from Mark Chamberlain, Microsoft Principal Developer Support Escalation. Now, this isn't to say that an update has been confirmed to be well on the way to consumers, but we are aware of Microsoft halting the current rollout of Windows Phone 7.8.
