Having same issue today on a Galaxy S23, with white blank screen on app login. Login on mobile browser (Chrome) and receive this Error: This XML file does not appear to have any style information associated with it. The document tree is shown below. I use the app all the time and this has never happened. Need some help to resolve.
<Error>
<Code>InvalidArgument</Code>
<Message>Invalid Argument .</Message>
<Details> POST object expects Content-Type multipart/form/data</Details>
</Error>
UPDATE: Sat July 22nd
Unfortunately uninstalling and reinstalling only worked for a day. I reinstalled on Thurs and was able to use Fri, but white screen is back Sat am on the app when I entered my passcode. As you all know, many are facing this same issue. I responded to my support ticket that the issue returned. Evernote Support, please fix.
