I'm on a Windows 10 PC using Edge (Chromium), Chrome, IE 11 for troubleshooting purposes. when I navigate to My Characters and select [View] [Copy] [Delete] etc... none of them work. There is no activity at all. If I right click them to load in a new tab it opens on the My Characters page again. When I Inspect Elements in Edge I see 7 warnings related to cross-site requests which I will paste at the end.

I haven't inspected elements in Chrome or IE 11 since they are yielding the same results, though I can certainly do so if needed. I am able to generate new characters successfully, but once they are created I cannot interact with them in any way. I've attempted logging out and back in repeatedly in all three browsers. I've created privacy and security exceptions in Edge for [https://www.dndbeyond.com], I've even tried disabling all browser privacy and security settings to troubleshoot and again logging out and logging back in. 

PC is brand new build, all software is updated as of last week (OS, Edge, etc all updated). Chrome is freshly installed as of last night (latest version).

I realize the language in the errors I pasted appear to be Edge specific, but I explained that the behavior is repeated on other browsers. So I will paste the same results from Chrome as well. One thing to note, there does appear to be some difference. There are 5 warnings and 1 error in Chrome, whereas the Edge results were actually 7 warnings (not errors).

This appears to be spontaneously resolved. Testing on all previously posted platforms and browsers shows that it is working with no changes applied on my end. 

Thank you.
