Recurring Jobs can be created in the App when you create a new job, however the Recurring Job Profile cannot be edited on the App once it has been created and will need to be done through the Web Portal. You will be be able to only edit the individual jobs that are created from the recurring job profile.
To create a new Recurring Job Profile via the App, go to Jobs > New or the + symbol in the bottom right > Fill out the details. Then at the bottom of the job creation page is the option to make a Recurring Job.
Any edits that you wish to make to the Recurring profile itself will need to be made through the Web Portal by going to Jobs > Recurring Job Profiles.
