when I try and login to my Dnd beyond account through twitch it’s giving me a invalid access token error! Anyone know any fix 

Same here...and since we are literally on the way to an area with no cel coverage, this is at an exceptionally bad time.

did uninstall and reinstall the app, with no success, in case that is offered as a suggestion.

edit: iOS 

app: 1.1.12.3

Manifest 16.0

It must have been a temporary service error - it seems resolved now, and I was able to redownload content

I’m having this error now as well. It seems to have popped up around when my subscription ended, and I needed to renew my payment.

There is currently an issue with Twitch's API. Hopefully, they will be able to resolve it soon. You can monitor their status here:

 Thus was actually the most recent bug report at the time you posted that comment, I dont know how you found this resolved one first.
