All MFA push notifications have suddenly stopped working.
All MFA push notifications have suddenly stopped working. This is affecting Okta, Duo, MS Authenticator and Authy. Notifications are turned on. I have reset network settings and privacy/location settings. I have updated the apps and iOS.
Most of the time if I open the app I can accept the push. I cannot register my device with MFA by scanning the bar code anymore.
iPhone 7 Plus, iOS 15
