Duo Authentication Prompt taking long to appear?

Duo for RDP

Duo Authentication Prompt takes longer to appear after doing a password reset. Has anyone experienced this? I’m not sure what would cause the 10-15 delay. I sent the logs to support and they can’t figure it out also.

We uninstall Duo, logged in with no issues. Re-installed Duo, logged in and the 10-15 sec delay persists. Any help would be much appreciated.
