Studio "show changes" function with git not available

We are trying to collaborate among developers but studio show changes function was grayed out. Check in forum maybe caused by .git/info/attributes that treat .xaml and .json as binary. delete such lines in attributes file is the correct way? or what other possible option to allow “show changes” to work?

After checking this
maybe “show changes” will not work after “Pull (rebase)” (why pull and rebase stay in the same menu as for git it is different… ^^)
Will test again and update here.
