Version 3.0 of the Flipbook plugin now uses the https://nodlik.github.io/StPageFlip/ JS library for the PDF viewer.
This version is responsive.
The control buttons use the FontAweome font (it's easier to override the button style, for example).
Your viewer overrides performed in the services/flipbook/pages/flashpageflip/book.xsl of your charter become obsolete.
Should they still be necessary, you'll need to report/rewrite them in a services/flipbook/pages/pageflip/book.xsl file .
You can delete the services/flipbook/pages/flashpageflip of your charter.
