"cannot authenticate maps. Contact the map content seller for help"

Brand new epix pro (51 mm). After connecting to Garmin Express for the intial updates (now on software version 17.23),  I am now seeing the following message  "cannot authenticate maps. Contact the map content seller for help" Despite the message, the maps appear to work properly. 

After a search of the forum, I found a similar issue in the past  where users were reciving a "cannot unlock maps" message in this thread--https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/epix-2/341035/epix-pro-gen-2-sapphire---cannot-unlock-maps-error-or-msg---why/1651457#1651457 

I have taken all of the listed steps in the "cannot unlock"  thread without success.
