Can’t log in – GroupMe Review

I had tried to log into my account on my new phone only for me to be logged out of my account from my old phone and I am unable to log in due to the fact that I have a new phone number. I have tried numerous times to try to switch it out and I just cannot. As much I understand this is for security reasons, I wish that we are able to verify through our email in consideration that they are linked to our phone numbers.
