As the count of background jobs to process increased, I started looking for ways to run more jobs per day. I thought that setting a workers count to greaer than 1 will process more enqueded and scheduled jobs in parallel, but I ended up with same job ran more than once. The app sends notifications to mobile devices and when workers set to values greater than 1 provoques clients to be sent the same notification several times. Any ides on how to fix this issue?
