Hi “Anonymous”
Your Google maps account is “Restricted” it means your account in Private so here we are unable to see your contributions (Reviews, Photos & Videos) only your followers can see your contributions.
If you want to turn off “Restricted Profile” just follow this steps :
1. Open the Google maps on your mobile.
2. Click on your profile (at top right side)
3. Click on “Settings”
4. After that go to “Personal Content”
5. Scroll down & at the bottom you see “Restricted Profile” with the On / Off button. From their you can off it.
After you turn off once check your profile by using another account or using “Incognito Mode.”
