Hello @Trishatishu,
Good question. In the past, the recommendation was indeed to open a browser session in incognito at the same time showing side by side another session being logged into Google, scrolling down simultaneously and all review, you do not see in incognito, would be those, being hidden. However, not so long ago we discovered, in incognito mode, you can scroll back only 20(?) reviews or photos. So that doesn’t seem to work anymore, but you can give it a try anyway.
But since your husband also a has a Google ID, the procedure with two sessions would work for you, if you can compare the sessions your are logged in with your husband’s.
If you are registered for the T100 system, it can show you easily. Otherwise opening an incognito session, can show you quickly by comparing the contributions with the number of posts in your profile:
As you can see in my case, 703 out of 707 reviews and 262 out 265 ratings are public.
The same applies to hidden photos and videos.
