Personal account. Forms will not let me edit etc

Hi, I’d first make sure you are signed in with the same personal Microsoft account that owns the form, not just an account that has a shared link to it. Forms can look like it opened correctly, but if you are in the wrong account or using a response link instead of the edit link, editing will be blocked. I’d also try forms.office.com in an InPrivate window, clear the browser cache, and check the form from another browser. If the form was created under a work or school account, a personal account usually will not be able to fully manage it.
