Has 21.19 Been Removed??

I installed 21.19, but it caused endless problems for me. Recovery hours messed up, Workouts folder 'Laggy' and Calendar widget 'Laggy' and 'Clunky' when displaying DSW's. To that end I reverted back to 20.22.

Reported all issues to Garmin support so decided this morning to reinstall 21.19, ready to send files if needed. Plugged into Garmin Express, synced, but the software is not found? Says I'm up to date with 20.22?

Has Garmin removed 21.19 in light of the reported bugs?
