Hello,
I have created a customized sales cycle and also created a sales stage, next I have assigned the sales stages to the sales cycles and also defined the probability, attaching the screen shot below.

However now when I am going to create the opportunity transaction in CRM Web UI, I am not able to see my custom defined sales stages attaching screen shot for your reference. Please advice if there is any missing configuration for the same.

Kind Regards
Atul
