During execution, either the selected device or the first matching device of a filter will be used and blocked until the execution
plan has finished. If the selected device is not available or a filter does not match any available devices, the execution
job stays in the queue until a suitable execution server and mobile device becomes available. Sauce Labs devices are not actually
single devices, but rather device types, so they are not blocked during execution.
To change or delete your mobile device selection at a later point in time, use the
Delete buttons, respectively.
