@Oanh-and-only-Oanh I've debugged this issue on production using user credentials you've provided.

This doesn't look like a Community App issue. It looks like the issue is with Topcoder Member Service or Topcoder Gateway config. In some reason request https://api.topcoder.com/v3/members/ladybosss?verifyUrl=http://www.topcoder.com/settings/account/changeEmail is not allowed from domain https://www.topcoder.com by CORS policy:

Btw, this issue is not reproducible in the Development environment I can successfully change email at https://www.topcoder-dev.com/settings/account.

from @urwithat:
The verify url is passed from the community-app to member api, we see from the error of CORS this is the request sent:
https://api.topcoder.com/v3/members/ladybosss?verifyUrl=http://www.topcoder.com/settings/account/changeEmail
the verify url is verifyUrl=http://www.topcoder.com/settings/account/changeEmail
its http, should be https
Should just be www.topcoder.com/settings/account/changeEmail

There's an issue in ES while its validating the email address for the member v3, you can go ahead and start using the member v5.
