😿 Pinpoint job stopped with an error.

The swarming task expired. The bots are likely overloaded, dead, or misconfigured.

Cannot reproduce.

WontFix.  This is disabling a new feature on older devices because of driver memory stomps.  This just "regresses" back to the old behavior that we have shipped forever.
