Point 5 is not add mobile number, but “Primary phone number”. This is part of the “edits” and will give you five points. More info about edits on: Suggest edits to a place or flag it for removal
Point 6 is part of Answer questions , and will give you one point for every answer
The uncover missing info follows the lines of edits. You get points once the change is accepted. The only exception is the photos where you get the points the moment that pic appears on your private profile.
By questions and answers do you mean replies in “know this place”?
Nowadays that behaves in a weird manner. The questions repeat. And I guess if your answer in the previous season is different from the current one, you may lose points. That happened to me once and then onwards I stopped answering those.
@KishorMali friends @C_T and @ErmesT have given right information but I’m give you a little more.
Firstly you don’t get points if the place already has those flags set. You also don’t get points if you edit, unset then, re edit and set them again.
I would also suggest to you that life isn’t all about points. I add accessibility information for the good of humans in general not to get points. I suggest you contemplate your motivations. Local Guides is about community.
