Situation
A fillable PDF was created to be used as a template when bidding jobs. The PDF was placed on OneDrive and the permissions were changed to read only as to not be able to save over the blank template. When the file is open on a PC with the Acrobat DC application, the file works as intended and the user is forced to "save as" and not allowed to overwrite the blank template. When opened on an iPhone or iPad, the read only permission is completely overridden and the blank template is allowed to be edited and overwritten.
