Unable to login in the latest version for iOS (v10.54)

Hi guys,
I'm unable to login anymore in the latest version of the App for iOS (v10.54).
It says my username does not exist! But on the website it's working well.
Can you help me with that issue.
Thanks.

Do you use email as username?

Yes, indeed I couldn't log in using my email address.
I just tried with my username and this is working.
Thanks.
