Latest update complete failure

Upon installing the latest Update from the App Store, the app became completely unusable. Garmin tech support said to delete and reinstall the app. After following their instructions the app now works, BUT I lost over 7 years of my saved favorite locations. As a regular business traveler who heavily relied on that information, I find this lack of QA from the Garmin App Team completely irresponsible. Will be moving over to google since I have to start over
