Someone sent me the link to sign up for vaccine. NO ONE should try this on a mobile device. The mobile version would have had me click the < arrow for prior month over 900 times to reach my birth date. Allow simple numeric entry like the web version. Went to web version. Went through all steps to sign up. It finds no possible dates, no matter what future date I ask. It needs a search function WITHOUT date specification. Or publish a schedule with locations and open dates. Quite useless at present. Please respond and tell me how I will actually do this. I am 77 yo with diabetes and heart condition. Could find nothing descriptive on your website.
