PTR Patch required

Was just playing a few minutes ago, then got a message saying a patch is required, close game and patch will automatically begin. So I closed the game, the patch did NOT automatically apply itself. Ran the Scan and Repair tool but that didnt fix the problem.
Game version: 2.6.8.66139, Region: Americas

same here it will not update

Im getting the update now, it finally became available in battle.net. (Going super slow though)

**Done updating, new version 2.6.8.66344
