Hello, I own Logos 5 for my Mac as well as using it on my iPhone and iPad. I am using notes on a new resource (Ryrie's Basic Theology) to prepare for a class I am teaching. I like to do my markup on my iPad (4th gen, iOS7) since if feels much more natural and aesthetic. However, on some sporadic occasions, it takes a significant amount of time for my highlights to "stick." By this, I mean that I can see the color covering the selected text (see comparison in fig. 1 attached), but all further highlighting becomes unresponsive until I either 1) wait for 15 seconds of so or 2) turn the page and then turn back.

Now I've read some on these forums that it might be due to a large note file or many notes connected to a specific resource, however neither of these are the case for me (only 3 pages of notes if printed; just started reading resource). I've wondered if it had anything to do with whether or not I am on wifi, but the result is sporadic under both conditions.
The strange thing is that sometimes the highlights show up almost immediately and at other times it takes a long time. If I want to change the color or add a note quickly, I have to switch pages and then come back to the current page to access the context menu for the highlight. This disrupts the flow of reading and notating.
Any help on this?
