How to schedule multiple cron workflows in temporal?

Considering an array of strings as input, my aim is to schedule cron jobs for each. I have tried creating custom workflow options and executing the same, for each iteration of input. Following this only the first cron workflow gets scheduled while other cron jobs wait indefinetely.

	for ind , sid := range ss_ids {
		var cronScheduleStr string
		if ind == 0 {
			cronScheduleStr = "* * * * *"
		}
		if ind == 1 {
			cronScheduleStr = "2 * * * *"
		}
		workflowID := "cron_" + sid
		workflowOptions := client.StartWorkflowOptions{
			ID:           workflowID,
			TaskQueue:    "cron",
			CronSchedule: cronScheduleStr,
		}

		we, err := c.ExecuteWorkflow(context.Background(), workflowOptions, cron.SampleCronWorkflow,sid)
		if err != nil {
			log.Fatalln("Unable to execute workflow", err)
		}
		log.Println("Started workflow", "WorkflowID", we.GetID(), "RunID", we.GetRunID())
	}

Apart from this I have tried child workflows in the same manner, but that also schedules only the first cron child workflow. It would be very kind, if someone can help out.

If ss_ids are unique, the first one should run every minute, the second one should run at the second minute of every hour, and the rest will have CronSchedule: ''.
