A Microsoft file hosting and synchronization service.
I'm having exactly the same issue as reported by the other users in this thread. I'm certain that its a bug with the redirect on the authentication modal that pops up.
To recreate:
Mac OSX Sonoma, latest build
Chrome 124.0.6367.208
- click the Personal Vault to open it
- Authenticator pops up on iphone
- Authorize through MS Auth app on my phone
- auth modal on browser is blank, never redirects to open the Vault
