I registered in Evernote with my Apple ID and used a “personal” plan. Recently, I changed my e-mail address in Apple ID. After this, I cannot sign in with my Apple ID on Evernote. It gives me an error message (attached). Then, I signed up with my e-mail (the same e-mail is in Apple ID), but there is no possibility to write to technical support from it. I write here to find the advice, how to solve the problem. Maybe anybody has faced similar problem or can invite technical/customer support representative to this topic. Thanks in advance, Annneta.
