To whom it may concern,<br /><br /> <br /><br /> I am contacting following a previous ticket you didn&#039;t answer. Following iOS 10 update, the iPad iPublishCentralReader app won&#039;t allow to change the font size in the ebooks.<br /><br /> <br /><br /> Here is the link from which I downloaded the ebook https://www-elsevierelibrary-fr.docelec.univ-lyon1.fr/product/neurologie74674. It is the &quot;Neurologie&quot; from Elservier Masson France. I access this link through my University&#039;s student login. It is the same as this one (no login required) https://www.elsevierelibrary.fr/product/neurologie74674. I have joined to this message the .ipef file in case you can&#039;t access the link.<br /><br /> <br /><br /> I&#039;d like to let you know that the very same problem affects all the ebooks I have (Cardiologie, Rhumatologie, Dermatologie etc.). I only download from Elsevier e-library so I can&#039;t test from other sources. <br /><br /> <br /><br /> I have tried to reboot the iPad, and delete + reinstall the application (and redownloading the ebooks). Nothing worked so far. Even changing the whole font size settings in the iOS global settings won&#039;t change the application font size.<br /><br /> So to put it in a nutshell : the bug happened after upgrading to iOS 10. I guess the whole thing can be called &quot;built-in font size settings in iPublishCentralReader won&#039;t work&quot;. Everything works otherwise, like changing the font. But not the size... <br /><br /> <br /><br /> Looking forward to your answer, because with such a small font the books are barely readable and I can&#039;t work.. otherwise I love your app. <br /><br /> <br /><br /> Yours faithfully,<br /><br /> <br /><br /> Guillaume Martin
