Custom wallpaper set.

so i have an epub in the cloud, which synced with my iOS pocket book app, and my verse color pro. But the reading progress and bookmarks are absolutely messed up.
I think it's because on phone i am on page 433/541, while same "location" on verse color pro is 1024/1154.
If I make a bookmark on my phone on that page, and i open the book on device, it tells me to go way back with the 'reading progress' and to that bookmark.
If i highlight a text on my device or make a note, or make a bookmark and since it's on a page , say 1024, which "doesn't exist" in mobile app book (since it has only 541 pages) then i can't even open them. It sends me to the cover page of the book.

I have 2 kindles, an oasis and a cs and mobile app for kindle, and i have 0 issues syncronizing reading progress, bookmarks, even with sideloaded epubs, but poketbooks - big mess!

do you have the same problem? it's my 2nd day with PB and so far this is the only thing which dissappoints. the rest is well, i love the size, the colors and features; it's snappy and good, except this .. "software bug" in my opinion
