You can change the amount of an already-existing diary entry—without having to add the item again—as follows: 

1. Click on the diary entry you would like to update.
2. Enter the new amount.
3. Click "Save".

Note: If you want to edit entries that have been imported from other apps, you need to edit them in the respective third-party app, not in YAZIO.

We hope that you were able to find answers to all your questions and wish you a great journey with YAZIO. Should you have any more questions, please feel free to contact our support team and submit your request here.
