Hi! I've been a daily user of Logos for 10 years now, and I encountered this unnerving issue for the first time.
In God and Money: Chapter One, only the leading part of the chapter is shown. If I scroll, everything becomes blank. If I scroll more, eventually the content appears (with a table whose rich content display might be somehow in cause).
See what I experiment: https://share.cleanshot.com/0x4Bx4PmLxfNV3pW0J4k
I reproduce the issue on my M2 Macbook Air with Logos 35, but not on the iPhone. I might try installing Logos on the iPad to read this book more comfortably, then, while you look into fixing the issue. Thanks!
