The new Apple iOS arrive on September 13, 2016.
That says « new version » also said changes and Apple likes that.
Unfortunately for us the version 10 use a different code.
The results are very simple, we have to rewrite the code for to run on version 10.
MrYay, the only one person who develops the application, did not finish to adapt it. I ask you some patience. It will end quickly.
Meanwhile, your application Booktubers will not work on iOS10.
Thank you all, Celine Blaché.
