I usually open the Google Maps Web in an incognito window. But I’d definitely try the App you recommended.
Just a quick question, if you happen to know the App workings - Does this App clears the data of web-view on close? Or the Search history persists over the usage? Apart from the android app data clear option, is there any internal auto-clear option?
See from the notification settings if this notification is categorized under some head. And if the category is not catch all, you may disable notification for that category. Otherwise blocking all notification or switching to alternative app would be the last option.
