If you don't see any history when accessing Google My History, the most likely culprit is that you aren't logged into the correct Google account. Tap on the profile icon in the upper right-hand corner and select the option to Add Another Account. Another problem may be that you've set your history for automatic deletion. This setting gets done on the "My Activity" page. Google lets its users turn off search history on their accounts or set it to delete data every 3, 18, or 36 months. No previous browsing entries appear when Google isn't storing your search history or if you recently deleted all records.
