Trying to set up to phone

Hi I just moved into my house and it has the rachio 3 and I’ve been trying for about a week now to set up to my phone. I’ve done the steps at least 50 times. What else can I do?!? Please help the dry season is coming

What operating system is the phone? What steps have you done and what has failed? Here are the steps I have followed and suggest:
