cannot login with a registered account

[bilaldemirer]

Hey all,

I have a mobile app and I am using Storefront API.

I have an account on my shopify store and when I try to login I get this error : 

 [{"code": "UNIDENTIFIED_CUSTOMER", "field": null, "message": "Unidentified customer"}]

When I try to register with this account I get this error:

 [{"code": "TAKEN", "field": ["input", "email"], "message": "Email has already been taken"}]

Any idea how to fix this or why this is happening?

The API returns same error:  [{"code": "UNIDENTIFIED_CUSTOMER", "field": null, "message": "Unidentified customer"}]

for both situations which are wrong password or not registered user. 
When I reset my password I am able login.

I tried to change my password, but error is still the same.

I logged in into store with my email(test@gmail.com) & have created customer in my store with the same email(test@gmail.com).

I need to get customer information via GraphQL, but it requires customerAccessToken.

So, I have to generate my customerAccessToken via mutation customerAccessTokenCreate.
While I'm trying to get access token with mutation customerAccessTokenCreate providing my email+password, I got this error

Please, help to solve this
