Describe the bug
When using a European date format, dayjs does not recognize the format and signs it as invalid date on Safari and Firefox.
When using Chrome dayjs recognizes the date but is then swapping day and month.
Link to codesandbox: https://codesandbox.io/s/mystifying-microservice-olpl6?file=/src/App.js

Expected behavior
Dayjs should recognize the European date format in Chrome and also Safari / Mac

Information

Day.js Version 1.10.5
OS: MacOS Big Sur, Windows 10
Browser Safari 14.1.1, Chrome 91.0.4472.106, Firefox 68.4.1esr

Hi @sagedemdreisbusch,
You need to use the CustomParseFormat plugin:

Same goes to 'DD/MM/YYYY' format. Just writing this here for other developer reference.

Why can't this be builtin into dayjs?
