The recent update forced me to delete the app immediately. Manual account registration did not work, instead I got stuck over and over again on the popup with the terms of service, despite I repeatedly tried to confirmed them with a tap on the corresponding button. So I had to try the facebook login (against my will) and at least that worked well enough to let me make screenshots of my saved wines and say good bye.
Updates should make software better, not worse. Lesson failed.
