I have SharePoint hosted app which contains several elements like list, Pages and workflows. In AppManifest.xml, In permissions we have enabled "Allow the app to make app only calls to sharepoint" and also we have apponlysequence in Workflow to elevate the permissions and run for all users. After enable this option, during installing the workflow, we are getting Click here to trust. When Site collection administrator tried to trust the app, he is getting " you do not have access to trust the app". Eventhough he is an admin of the site and not able to trust the app. Please help me how to resolve this issue.
