Hello,
Since EasySocial 2.1 and the Mobile Web Template 2.1, in the Group/Page/User App, on Mobile there is no more link to create a new Blog Post or Create Discussion.
This concerns EasyBlog Group/Page/Event/User App, and EasyDiscuss Group/User App.
On Desktop, your new structure that puts the button on the top right is a success

. It is consistent with other applications.
On Mobile, the ideal would be a link/button in a Filter menu (icon on the bottom left), as for other native EasySocial applications.
Please see captures in attachments.
Thank you,
Philippe
