Resuming Scheduling

I have a Rachio-EBED42. I had my lawn fertilized and given weed control Wednesday. I was asked not to water for two days, so I went to Wednesday and shut off watering for that evening. I then shut it off for Thursday, but now the whole schedule has disappeared and I don’t know how to get it back. If someone who understands this can help, I’d sure appreciate it. Thanks in advance.
