On MSDN Microsoft Engineer Mark Chamberlain has confirmed that Windows Phone 7.8 Live tiles can have issues, saying the problems have been recorded and are understood.
He noted the Live Tile bug can cause two problems:
1. Live tile causing continuous web requests (and side effects such as battery drain)
2. Live tile failing to update.
It is of note that the first one can cause data overages and therefore be very costly to users.
Fortunately Microsoft is considering releasing a fix as an OS update with Mark saying â€œfixes will be considered for inclusion in an update to the phone operating system.â€
I would say the issue has some urgency due to the data usage bug. Of course we have heard the roll-out of WP 7.8 has been halted in Germany, though we do not know if this is the case elsewhere also, but I think at the very least Microsoft needs to put out a blog post informing and warning Windows Phone 7.8 users of the issues and risks.
