I was about to post my own question about this, before seeing this earlier post. I've had the same small but annoying problem for over a year - clicking the icon on my iPhone (iOS 11) gets me to the "Already a member?" sign in page, where I click Log in, then, with user name and password remembered, I'm taken to the Home page, and I click My Bookshelf recipes. Three clicks instead of what should be one to display my recipes page. I deleted the icon, cache, and reinstalled using the bookshelf recipe page, as Jane suggested, and it now begins at the "To create a Bookshelf you need to become a member . . . it's Free!" page. Then two more clicks again.
Are we doing something wrong? We - belljaf and I - can't be the only two users with this problem ...
Thanks,
Ed
