The mid-season patch has been delayed to an unspecified time.
Overwatch 2 Mei

On October 31, Blizzard gave Mei mains at least one reason to be afraid. It was that day when Mei was disabled in Overwatch 2 due to an issue with her Ice Wall ability letting players access inaccessible places and out of bounds areas in maps. A fixed Mei was set to return as part of the mid-season update, but that patch has now encountered some issues of its own. That update was initially set to be out today for players.

Blizzard took to the forums to say that the mid-season patch has been delayed due to an unspecified "critical issue." They were not clear if this critical issue related to Mei or to some other component of the update.

As part of the delay announcement, Blizzard says that they will provide an update on the forums when the issue has been addressed and the update is ready to roll out. Specifics on the update were not shared yet either, but a general overview was shared on what players can expect when it eventually goes live.

This includes the upcoming balance changes, bug fixes, including those that affect Mei, and core content updates we have planned for this patch. This delay also impacts the delivery of Overwatch League Viewership Incentives & Perks from the Postseason matches during the period between Oct 30 - Nov 4, along with the rotation of cosmetics in the Overwatch League shop.
Don't worry though, the regular schedule of updating daily and weekly challenges went through without issue. Also, the in-game shop has been refreshed, so be sure to get those wallets ready to throw money at your screens.
