Adobe Acrobat for Google Drive App: No Save Button

Yesterday, we noticed an update to the Adobe Acrobat for Google Drive App that must have happened Wednesday night.  Thursday, the Save button was gone and some of the content that was typed into files was gone.  Today, we have to wait a good minute for the changes to be saved when filling in forms using this app.  When trying to exit the tab, we are prompted with a message stating, "Changes you made may not be saved."  Is anyone else experiencing this issue?  If it is going to save automatically, that is fine.  However, it shouldn't take that long to save!
