Note to self: Mustard_ Sowing Seeds of Fun and Faith Vol - Shepherds Voice.epub

[mickael-menu]

I can't reproduce the issue from develop or the last released version with the sample. Do you have an LCP-protected version to share?

Also there are no references to g_font_10.ttf at all in the EPUB. Are you sure you shared the right version?

[ajay9889]

@mickael-menu the same book we also tried it works but the .LCP file is not working... Please find the link of LCP file which i have pasted on the slack channel. iOS is getting load, the font issue will be

Still no issue for me with the LCP protected file.
