Hi, we have site facing multiple login issue

When logging in via Google in the mobile app (WebView), an HTTP 400 error occurs.
When logging in via Google on the web version, a 503 Service error appears. The expected logic is that if the user does not exist, they should be created automatically.
After successful login via email (OTP), the user’s first name and last name are not displayed in the account details fields.
When updating account details and saving, the changes are not applied (needs to be checked both in WebView and on the web).
multi language and currency need to adjust
Integration of the "Supported Devices" page.
