Unable to Update Virus Definitions

Is anyone else having issues updating their virus definitions? I keep getting an error. I have rebooted, there is just a generic message saying "Something went wrong and the update failed. Please try later. No indication of what went wrong or why. This is disappointing in the extreme, usually Avast updates automatically. Is this a known issue?
TIA
Kevin

Which Avast Product and which version?
Have you tried doing a “Repair App”?
