Reminders?

Options
Hi there! I'm not exactly new, but. I haven't been on here in almost 2 years! We'll the good news is that I'm back and hopefully this time for good! I have 66 pounds to lose and I'm taking it slow.
Anyway, I do have a question about the reminders, I have mind set but, I never seem to receive them. I was just wondering how they are sent? E-mail, text or somewhere on here. I'm using the app. On my phone if that helps!
Thanks in advance! I look forward to supporting you and receiving support and advice as we take this journey together!
Please feel free to add me!
