After the latest Windows Update - Merlin no longer accepts any pdf files uploaded from device due to "non accpeted format". I understand this could be microsoft recent changing the format listing from simple PDF to PDF + based on default PDF Viewer (which i guess is on them - photo attached). However, for me, and likely all windows users, this has resulted in one of my PDF Files being accepted by Merlin during this crucial exam revision time. Pls Fix / help ASAP pls thanks :)
