Map update stuck in download queue

With my Forerunner 965 I think I am hitting the Map Manager Issue reported in this closed thread: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-955-series/311253/maps-manager-bug#pifragment-1279=4

My Forerunner 965 runs 17.26 and I have installed TopoActive Europe via Garmin Express which installed version 2023.10 and reported all Map are up to date. After the Install the Watch reports 16.5 GB storage left. According to https://support.garmin.com/en-US/?faq=LR6HR5Xul6A9zoxySC5KM9 2023.10 is the current version of the Map however the Map Manager on the Watch says there is an update available and when I try to install it it remains in queued state.

1: Does your watch's Map Manager show "Update Available", but Garmin Express indicates that the maps are already up to date?
