I liked this app until I bought iphone7

I love that this app synced with my calendar and its easy to use. Yesterday I bought an iPhone 7 and I cant log in, sign in, retrieve a password or even create a new account it no longer works with my phone AT ALL. I get an error message each time saying LOGIN FAILED "the data couldnt be read because it isnt in the correct format" Disappointed. Would have given it a 5 now its a one.
