[BUG] Date display/input format mismatch

[Woebin]

Describe the bug
Reading dates are shown in dd/mm/yyyy format, but when changing the date via input (i.e. not using the calendar element) it's parsed as mm/dd/yyyy.

To Reproduce

1. Open details view on a book in your collection.
2. Go into edit mode.
3. Edit "finished reading" date.
4. Hit the pen icon to switch from calendar view to manual input.
5. Input date, e.g. "12/01/2020".
6. "Finished reading" date is now set to the first of December, 2020, and displayed as "01/12/2020".

Expected behavior
Expected input format should match display format.

Screenshots
Will provide on requires if the description isn't clear enough.

Additional info(please complete the following information):

• Manufacturer and model: OnePlus A6013
• Android version: 11
• App version: 2.2.0
• App source (F-Droid, Google Play, Github): GitHub via Obtainium

Additional context
Ideally, date format should be up to the user and not locked into any default. Whichever format is used should be consistent throughout the app (input and display should match).

Same issue for me

It would be nice if you could choose a date format, either

mm/dd/yyyy
dd/mm/yyyy
yyyy-mm-dd

Dates are displayed dd/mm/yyyy in the app. When you edit the date manually through the picker I suppose it dynamically adjusts to your locale settings. I'll dig how to make that coherent

Alright, from now on the displayed dates (in book screen, in the list etc) will follow devices format (same as the one in date picker)
