Cannot login on app – Blood Donor American Red Cross Review

I downloaded the app knowing it would make appointments easier. I want to donate more often because blood donations saved and could have saved my family in certain circumstances and I want to be able to help someone else’s loved ones have an opportunity as well. I downloaded, deleted, restarted my phone, downloaded again and it keeps telling me it cannot sign me in. I even reset my password online and it works well on the website but I cannot get the app to cooperate. I have no idea what the app is capable of since I cannot get through. Please help.
