The Queuing duration is determined by the number of processes running in the background.
You might notice sometimes your process runs within minutes while sometimes it will take an hour. This is because there are many other users are in the queuing process.
What can you do if your process is queuing for too long:
1. Wait for a moment and check if it is running.
2. Contact Support from the widget, they will check the situation.
Typically the queuing process might take a while but it will surely complete the process. Better late than never.
If you don't feel like waiting, you could always turn on the Email Subscriptions in the Preferences.
