Alexa not responding, pulling second hub devices

Alexa is now saying that it can’t find lights that worked fine the other day. I discovered devices again and multiple lights report offline in the Alexa app.

Additionally, I disabled and re-enabled Smartthings in the Alexa app and only authorized my hub, yet a shared hub is also populating my list in Alexa. Currently, Alexa is useless with SmartThings. Has anyone else seen this issue?
