I am having the same issues but I do not sign in via Apple ID, I sign in via Evernote. Notes are appearing blank and will not load.
Upvoted request. I am a UX Researcher, and the lack of in-note table of contents functionality limits my ability to use Evernote for work docs. My stakeholders need a TOC to jump to their priorities to even consider reading a document (otherwise they become overwhelmed and do not read a word of my report). Right now, I have to opt for Google Docs. I imagine lack of TOC is a deal breaker for businesses considering Evernote. Thank you.
